You're a manufacturer of turbines, medical instruments, plastic molded automobile parts, consumer packaging, left handed wrenches...you name it, and you have one large customer and many smaller ones. Does this sort of kind of describe your company?
So, it makes sense that if your one large customer uses SolidWorks (or Inventor, CATIA, NX, Pro/E...), then you should copy-cat their CAD software for your company's manufacturing engineers or CAD operators to SolidWorks, right?
On the surface this seems like a logical and sound decision. After all the file formats are the same, so it should be really easy to open the product file(s) and begin making the necessary changes to the final part/assembly file(s) in order to manufacture the product.
You would think so, but it's not the case. Why? Because there is this HUGE thing in most of these CAD files called History. History is what gives SolidWorks (or the software in the previous list) the ability to create the CAD model. It is the history of the operations of the product designer/CAD Operator - every click, every feature in the exact order that they were created, which once run in the program, gives you your completed CAD model. This is the case for History-based CAD, of which most of the world is using today.
Once the Manufacturing Engineer/Manufacturing CAD Operator receives the history based (SolidWorks) model, she has two choices
- Begin to search through the history of the CAD file to try to reuse the design in order to come up with the geometry necessary to make the edits required for the manufacturing operations. And if she fails at this, she needs to resort to option 2...
- Redesign this prodcut from scratch - using the product file as reference geometry in order to create a CAD design that can be machined, or to design a mold, casting, fixtures, dies or whatever the manufacturing operations are necessary.
Smart manufacturers give their manufacturing engineers another option: Import the SolidWorks file (or native history-based file) into a Direct CAD modeler. This modeler reads and understands the geometry without the use - or even better, the need - for history. The manufacturing engineer can then edit the CAD model as she desires in order to manufacture the product.
So, what appears to be a logical and safe deicsion: using the same, copy-cat, CAD software as your largest customer, can actually be a very large mistake that will cost you time. You will lose time with CAD operators. (Estimates say that up to 50% of CAD operators time is spent fixing files! Multiply the annual salary of your CAD operators times 50% and see how much time and money you are wasting!). You will lose time when edits are needed for manufacturability or when product revisions force changes (which could derail the entire product production schedule).
Being copy-cat when it comes to your CAD software will cost you time and money. Wise manufacturers chose direct CAD and save.
There are many other issues to consider when chosing the right CAD software for your manufacturing business. Want to learn more? Download Direct CAD for the Contract Manufacturer. Discover the advantages Direct CAD software can give your business.
Are contract manufacturers adopting Direct CAD? You bet your boots they are. And that means good things, especially for companies that need to gain speed and agility to remain competitive. Longtime users of history-based CAD are no longer willing to accept complex, inefficient and inflexible software. Sticking with the status quo just isn’t cutting it anymore...
There are many factors that drive company and user decisions: comfort in the popular names, comfort in numbers, fear of dropping the status quo, basic fear of change, etc. Even though we are 2nd and 3rd generation users, perhaps we simply cannot imagine there is a better way to do things. After all, the tools are being produced by the financially successful vendors – how could it be wrong? But no matter, the collective blinders of the past are coming down – and users are changing in spite of the 25 years (talk about history!) of being sold variations of the same approach over and over.
Pain & Relief…
While they may have not realized it, many customers are in pain, sometime seriously so, and it is affecting their bottom line and viability. For these users, particularly in the ranks of manufacturing, there is a clear frustration with the status quo, and rising concerns about stability, poor performance, lack of support, and perhaps most important - difficulty, or inability to reuse product data from customers, or even legacy files! Thus, the motivation to seek alternatives continues to grow. And what they are finding is there are new tools – ones that dramatically improve their overall performance! So as they test the waters of Direct CAD more they are finding relief and the word is spreading…
Due to ever increasing competitive pressures, contract manufacturers are showing more resilience and willingness to seek alternatives. When they evaluate solutions like KeyCreator Direct CAD, and assess the tasks they truly need to perform, they see the simplicity of Direct CAD in a new light. They are starting to recognize how flexible direct, non-history methods are compared to tools of the past…
Making it meaningful
There are many issues all CAD developers face when they try to switch paradigms to address both direct and history methods well. A key issue is that they simply are resisting unlocking the strangle-holds they have on their customers. Instead of solving the data openness and usability issues many customers need, they give lip service or disguise their motives with schemes such as ‘members only’ cloud communities.
Mature products also are larger programs with more complex code. Their stability and overall reliability become rarer commodities. Another issue with mature CAD products is the loss of focus on core competency; trying to ‘do it all’ often leads to average, less productive solutions over time… the bells and whistles become both smaller and less loud– and certainly less meaningful!
The relatively recent progress of the simpler, less complex CAD products such as KeyCreator Direct CAD are proving to be a boon to certain industries - especially resourceful contract manufacturers.. Smaller CAD companies understand the benefits of this approach, meaning they are making their design tools more accessible, not less so, which means users aren’t stuck with unnecessary complex operations (that truly only benefit software companies).
In summary, we are seeing more and more ‘users embracing a simpler, more efficient and direct way to get this done. By using Direct CAD to accomplish their tasks, I hope users continue to drive all software vendors to rethink how (or if) they can better serve the end users while still being successful. Sound too altruistic? Perhaps, but you have to have a dream…
So people often ask us, is this ‘Direct CAD’ stuff easy and relatively quick to learn?
To me the answer is most emphatically yes…
To begin, if you have been involved in the engineering, design, or manufacturing fields somewhere during the last 20+ years or so there is a very good chance you have been exposed to at least some CAD principles, whether in school or on the job. This means that you have at least seen, or used some of the tools used to work with 3D digital models on a computer screen…
Obstacles to learning Direct CAD
However one hindrance to adapting to Direct CAD (which I can speak of from my own experience) is due to the prevalence and longevity of history-based tools. Users coming from this world may find the simplicity and resultant efficiency of Direct CAD to be quite foreign – at least at first!
Another hindrance comes from the fact the majority of colleges and technical school limit exposure to only a few popular CAD tools resulting in an insular view and understanding of what is possible. Students [and instructors] get locked in to one way of thinking without knowing the alternatives. In these cases the biggest challenge to learning Direct CAD is unlearning the one approach they may have been indoctrinated with.
Designing by visualizing shapes – Only need to learn a handfull of commands
But going back to what it takes to learn Direct CAD. Our brains and creative process tend to think of designing by visualizing shapes that will ultimately have a specific set of desired behaviors.
With direct modeling you can perform a majority of the solids based mechanical design by learning just a handful of functions. In the case of KeyCreator, you can create mechanical [vs. free-form surface] designs largely using just the following few commands:
- Dynamic primitives – the ability to quickly create most analytical shapes on the fly
- Dynamic face – a sculpting-like tool to shape solids in real-time
- Remove face – a simple tool to remove unwanted features – as part of the creative process
- Boolean add/subtract – like sculpting clay, the act of adding and removing material, or shapes from one another
- Direct dimension editing – a very intuitive, simple way to shape your results with numbers, or dimensions
- Dynamic transform – a fast, intuitive way to move things around, align and organize your data
- Feature recognition – very fast way to perform mass edits on tradition mechanical features such as pockets, screw and bolt hole patterns, etc.
All of these tools will allow you to create most mechanical part and assembly shapes with virtually no, or at least far less need for traditional wire frame [curve/profile] tools.
Other considerations when learning Direct CAD:
Order of things: Direct CAD allows you the freedom to create without concern, or even paying attention to the order of the steps you take to get there. Simply create objects and features as you go…
Sculpting: Direct CAD offers the closest thing to shaping your designs, much as people working with clay or carving wood models but using virtual, dynamic shape modification tools. Tools like dynamic face, Direct Dimension Edit along with adding/subtracting shapes provide a natural way shape your designs into reality.
Primitive based methods: with tools like dynamic primitives and Booleans you can start with simple ‘building block’ shapes [curves, or solids], then simply add and subtract to create more complex shapes and designs - much as model makers do.
Conceptualize then get real: Direct modeling tools allow you to ‘sketch’ your ideas quickly then allow you to ‘numerically harden’ the fit, form and function values as you go, or later after the basic concepts are complete. This is the beauty of direct modeling design - no pressure to use a specific formula or method to get the best result!
Let’s get physical: When creating designs in Direct CAD you simply slice, dice, add and carve away material – a natural way to evolve your design ideas – all using just the tools above….
Reuse: Since direct modeling tools are all focused on geometry you can also start your work by reusing existing data, whether legacy, catalogue items or other imported data.
Change anytime – no problem: Making changes to current projects, as well as legacy, and imported ‘dumb’ files from other CAD systems using intelligent feature discovery is another major reason learning Direct CAD is easy.
Intelligent feature and face logic tools make finding and editing sets of features and faces a snap compared to cumbersome history based methods.
Direct face editing is very much like sculpting simply drag, revolve, and snap to locations as needed!
From a CAD learning perspective, there is no better or easier method than ‘direct.’ Consider picking up a design you, or one of your co-workers did 6 months ago, or even longer and simply being able to select the faces/features that need changing and simply doing so vs. searching and debugging a potentially flawed history tree?
Is Direct CAD easy to learn? Absolutely.
Once you learn seven basic commands and understand Direct CAD’s intuitive design process you will be designing like a Pro. Adding Direct CAD is not only easy to learn, it’s easy to use and can have a lower cost than history-based CAD.
As a long time soaring enthusiast (Hang Gliding, etc.) I have a love affair with clouds – silently gliding from cloud to cloud unfettered by the burdens of the world below – to me this is the ultimate high!
Clouds, of course can be beautiful and even freeing. Consider soaring birds (or hang gliders) gracefully climbing, freeing themselves from the bonds of earth and gravity, gliding effortlessly from cloud to cloud under a beautiful lazy summer day. Clouds can also be downright frightening, as witnessed when Cumulous-nimbus thunderheads make their dramatic appearance, which not only can take down virtually any flying object, but wreak all kinds of other havoc… And in the context of cloud based CAD and file sharing, clouds may even can take on an “Orwellian nature” - consider the recent disclosures about our NSA surveillance! But I digress; let’s look at the recent offerings from both CAD and other collaboration-driven companies and what their cloud offerings may mean to you and me. I wonder, are we about to experience a time of openness, unfettered access to share data with our clients using the tools of our choice, all which could make us more effective than ever? Or are we looking at the creation of more exclusive clubs with restrictive membership rules and policies?
Clearly high speed internet/web performance and improvements in sharing applications have enhanced the experience and potential for design collaboration in real-time and perhaps has made design data more accessible – or has it? Cloud-based CAD applications and related technology promise a number of benefits: simplicity of deployment and maintenance of software and unique opportunities to collaborate and share our designs, both visually and in real time to name a few. Cloud-based CAD is being embraced by several of the larger companies and of course some smaller/newer players, as well as companies who are focusing more on crowd-sourcing/sharing/collaboration vs. the CAD app itself. Others are choosing to offer a new/old idea of subscription services for the use of their software as an alternative to purchasing. Simply download, install, commit to a year and pay the monthly rental fee via a web store and off you go… (Hmm, is this really saving us money? Read the fine print!)
But in spite of all the potential benefits, is the cloud being used as just another way for software vendors to lock users into their private communities and solutions, while selling the privileges and benefits of renting time on their respective clouds? The idea being you can more effectively collaborate and perform at least some editing of shared designs – assuming the host allows you and only if you belong to their particular cloud… Instead of providing a true open door policy where companies and users are truly free to use a broader selection of tools, isn’t this just another way to ensure you stay in a given vendor’s world?
At Kubotek, we have this odd notion that one of the true benefits of direct modeling and cloud-based apps is the potential for companies, their customers and suppliers to truly engage in a mutually beneficial community – a community where design-through-manufacturing projects could be best addressed by allowing members to bring not only their considerable domain expertise, but to also use the tools of their choice.
So wouldn’t a truly effective, cloud-based design and manufacturing community best be served by an open-door policy where all data, regardless of source could be shared, viewed, interrogated and editing by project members regardless of the tools they wish to use? I have to think such an open community could really expand our potential for collaboration, design crowd sourcing, etc. while helping individual contributors to be more effective…
And as for the tools used in the cloud, Direct CAD modeling software is still the best option for open sharing and collaboration; history methods simply do not lend themselves to sharing and working with CAD models and assemblies effectively, particularly if members are working off of neutral file formats [STEP, etc.] or even mutually agreed upon “native” CAD formats. Sharing history-based CAD data, regardless of whether it is based on web-hosting, subscription or simple file sharing, is still rife with cumbersome, difficult to understand editing tools prone to a variety of rebuild failures – and that is assuming everyone is on the same software and version!
Yet it seems doubtful the larger CAD/CAM/CAE vendors would want to offer such an open community where anyone could join and still be allowed to use the tools of their choice. No, quite the contrary, the message so far seems to be join us or, as the Rolling Stones song said, “get off of my cloud…”
Now before I am accused of communism (or worse), I fully acknowledge we all want to keep our customers and grow our businesses. The question is how we go about doing this? Do we continue to strong-arm customers into using only our solutions in whatever way we deem appropriate, or by pushing what is most popular, by virtue of company size – or should we be allowing people to choose solutions simply based on what will make them most effective?
Matt Carr is VP of Sales and Support at Kubotek. As a 30-plus year veteran of CAD industry, both as a user and from the vendor’s side, Matt has witnessed a fairly complete history of the CAD industry.
Why would anyone in manufacturing industry not use direct modeling CAD tools? (Or any design discipline, for that matter?) I was thinking about this and how there are still so many shops unaware of the CAD “alternatives,” or they still struggle to open their blinders. After all, they are already using a mainstream history-based solution and believe it to be the best and only solution. But is it?
So this got me to thinking about the evolution of CAD tools for manufacturing, and how the “new” generation of Direct CAD is still relatively unknown. How many people still do not realize what a highly productive alternative or even complement to the current CAD products Direct CAD can be. In particular I wonder how many contract manufacturing firms have considered the effect on overall performance and bottom line by not having direct CAD in their arsenal.
A major reason manufacturers should consider Direct CAD is how we conceive and create designs. Not that long ago, pencil and paper (or drafting) was the primary method of capturing such design intent. (And it still is the primary method for many!) Conceptualizing and immediately putting ideas down on paper offered a very natural way to visualize and create our designs. This is a pretty straight forward process in that we imagine, and then simply draw our ideas - depending on our skill - to express ideas in the form of blue prints. Of course this evolved into electronic layout drawings or 2D CAD which gave us a new ability to cleanly express our ideas (no need for good artistic skills), and perhaps, more importantly, it gave us quicker ways to edit/recreate design intent – and thus, the first “Direct CAD” modeling was born.
This ability to capture our thoughts easily in electronic form was in fact “direct” since we could interact directly with the geometry by deleting, trimming, breaking, moving, etc. Eventually the new generation of direct dynamic editing tools allowed us to “physically” work with complex 3D design content – the ideal approach for manufacturers since it is the most intuitive approach. This is particularly important given that manufacturing is downstream from product design and must produce tooling (and products) with never-ending pressure to do so for less money and time.
But early on, CAD technology diverged into another modeling method: history-based feature modeling. This was not just a disruption to the current process, but it created a veritable storm in our creative process, not necessarily a good storm. It came about when PTC finally launched Pro/Engineer, the first commercial history-based feature CAD system circa 1988. The world was understandably awed by the seeming magic of being able to edit 3D designs without tediously having to break apart and reconstruct complex geometry – particularly 3D geometry.
While direct geometry modeling was still evolving based on the work of a few pioneers (HP’s Solid Designer, CADKEY, etc.) no one could stem the rush to history-based methods once it got rolling. And so from a market share view, the yet unfulfilled promise of Direct CAD essentially went into hibernation for a number of years.
From the software vendor’s side, we probably should have considered how much we were offering in the way of improved tools to create, engineer and manufacture products. For the most part everyone blindly charged like a buffalo stampede down the path of “history” modeling, all attempting to offer similar tools, yet with all the same burdensome, costly restrictions…
Anyway history is history (no pun intended) and as a result, I am convinced we lost significant flexibility which in turn has had significant impact on how productive we are – particularly from a manufacturing view. And how much has this cost us?
Meanwhile the next big “change” in the CAD industry primarily involved lowering the cost of the software and offering it on relatively inexpensive PC’s – while this was a very effective business model it further put the awareness and promise of direct modeling in the background.
But did we really understand how much we lost by unilaterally embracing what is arguably a very unnatural way to work with CAD? To achieve the “magic” of editing complex 3D models using history-based methods, manufacturing users had to try and work with overly complex, order-dependent, formulaic, and rigid constraint-based files to build tooling assemblies and fixtures – a difficult, inflexible process at best. Even worse, this method further locked users into fewer and fewer vendors with less opportunity to effectively share data.
Perhaps the biggest downside of this approach was the lack of effective ways to manipulate files from different CAD systems (aka “dumb” geometry) without essentially rebuilding designs from scratch. This has proven to be much too costly whether trying to manage up-front design change, or more importantly for those manufacturers dependent on this history-constrained data. So what were their options: purchase a number of different CAD systems, then hire and maintain all the staff/expertise to operate these different CAD systems? Clearly not effective either. And the notion that if most of my customer files come in one format, then I simply need to use the same system is equally false. While the vendors love, and still very much promote this idea, it is also bad for number of reasons – it prevents the “data openness” needed for manufacturers to take on more types of work to become more productive and profitable.
Before all the champions of history-based CAD come at me with your torches and pitchforks, telling me how your superior expertise makes you masters of your parametric universe (and BTW, I consider myself as having been such an expert once), tell me how effective are you at handling models created by co-workers, let alone projects from outside your company? From my own experience (and for those willing to admit it) it can be challenging to manage even your own designs, particularly as the complexity grows – debugging history, constraint and mate errors often lead us to throw up our hands and start projects over. Again, how much lost time and productivity has this cost all of us?
The good news is since true Direct CAD works explicitly on the geometry and does not rely on any history order dependencies for recognizing and making changes, it alone offers respite from the tedious drudgery of history-based modeling’s arcane work methods. In fact, it is the most natural transition from the aforementioned pencil and paper. Direct CAD alone offers the industry the most open and flexible toolset to work with different CAD formats, and does so using physically intuitive tools that truly save considerable time – this is a gold mine for manufacturing.
One of the most common questions that we receive when at trade shows or from prospective customers is: How is KeyCreator different from SolidWorks?
A complete answer to this question could go on for many pages, but let me try to make the comparison as simply as possible.
First, how are they the same?
Both KeyCreator and SolidWorks are CAD software programs. You can use either program to document the design of a product or mechanical part. Both can create drawings, both will get the end result completed.
Notice that above I used the phrase "document the design." In SolidWorks, you can indeed design a part, but its best if you already have a design in mind, on a napkin, in a 2D sketch or somewhere else before you begin to describe it in SolidWorks. Conceptual design, the creative process of developing your design, can be done in SolidWorks, but it can be very cumbersome and time consuming, requiring starting new designs from scratch for multiple design iterations.
Why isn't SolidWorks a good conceptual modeler?
The reason is that SolidWorks is a history-based parametric solid modeler1. (See Wikipedia's definition below). In SolidWorks the relationships between the objects and features are programmed into the design. This is called design intent.
And with history-based parametric modeling, objects, features and their relationships are represented in a History Tree. This keeps track of the order, location and relationships that are programmed. Programming the design can be difficult. Determining where to start the design and how to program the relationships requires a lot of skill and practice. If changes are desired while programming of the design, or if modifications are needed in an existing design, then it is necessary search the history tree to find the objects and relationships where the changes would need to take place within the history of the design. In a complex part design, this may mean searching through 100's of features or more.
Partial History Tree in SolidWorks
Once the features are found and if the design was programmed to accommodate the changes, then the system rebuilds the design to the new specifications. Sometimes rebuilding errors occur or the software crashes. Then the change must be made another another way, or it is necessary to reprogram the design from scratch. No programmer is going to be able to anticipate every change that may be required in a design. This is why designs get reprogrammed many times when changes are required.
If designers are working with very mature designs that need few changes and if programmers are very skilled then SolidWork's history-based parametric approach will work fine for the organization.
Why is KeyCreator a good conceptual modeler?
KeyCreator is a Direct CAD Modeler2. (See Wikipedia's explanation below)
What does this mean? It means there is no programming involved. There is no history tree involved in the design. The design is strictly defined by the geometry contained in the design. Relationships are not fixed. They can be changed at any time in the design. This makes KeyCreator an excellent conceptual modeler. There is no rebuilding, because the design is always up to date. This means that a designer can make as many changes and try as many options as their mind can conceive. This inevitably leads to superior designs in less time.
KeyCreator Direct CAD not only allow ease of conceptual design, but it also allows ease of comparison of CAD designs based on the geometry of the design. Comparison tools graphically show differences between to similar models to check for changes in designs - intended or unintended. This allows manufacturers in the supply chain to confidently plan for changes or to communicate suggestions for enhancing the design to improve quality or cost.
KeyCreator's Direct CAD architecture also enhances the ability to optimize designs for machining and tool making. And with KeyCreator's integrated machining package, changing designs in KeyCreator carries through into KeyCreator Machinist. This allows the machinist to try multiple designs and machining strategies in a seamless manner. This leads to better design and better machining strategies.
Lastly, today's leading edge designers are optimizing their designs up front in the design cycle by using CAD simulation. KeyCreators fully integrated KeyCreator Analysis program allows the designer to try many approaches to the design and quickly run multiple analysis without the need of exporting and importing files into another software package.
There are many other differences between KeyCreator Direct CAD and SolidWorks history-based parametric CAD. Feel free to mention some in your comments.
Thank you for reading.
1. Computer-Aided-Design Wikipedia http://en.wikipedia.org/wiki/Computer-aided_design 3D
parametric solid modeling requires the operator to use what is referred to as "design intent". The objects and features created are adjustable. Any future modifications will be simple, difficult, or nearly impossible, depending on how the original part was created. One must think of this as being a "perfect world" representation of the component. If a feature was intended to be located from the center of the part, the operator needs to locate it from the center of the model, not, perhaps, from a more convenient edge or an arbitrary point, as he could when using "dumb" solids. Parametric solids require the operator to consider the consequences of his actions carefully.
2.Computer-Aided-Design Wikipedia http://en.wikipedia.org/wiki/Computer-aided_design 3D
Some software packages provide the ability to edit parametric and non-parametric geometry without the need to understand or undo the design intent history of the geometry by use of direct modeling functionality. This ability may also include the additional ability to infer the correct relationships between selected geometry (e.g., tangency, concentricity) which makes the editing process less time and labor intensive while still freeing the engineer from the burden of understanding the models. These kind of non-history based systems are called Explicit Modellers or Direct CAD Modelers.
Linked-in has a couple of interesting articles today on manufacturing and corporate responsibility, the first was by Jeff Inmelt CEO of GE entitled Why We're Betting on Manufacturing
Inmelt's article discusses the drivers to turn the slow American recovery into a long and sustainable boom:
1. The rich reserves of shale oil - this can be sped up with a North American Pipeline.
2. Applying social media to the industrial world and creating a social internet for manufacturing.
3. Speed and simplification
4. The evolution of Advanced Manufacturing
As part of this evolution of Manufacturing, he mentions using new technologies like 3D printing of jet engine parts and the rise of analytics and software.
I couldn't agree more fully with the CEO and Chairman. One of the driving forces of our company is to increase the productivity and knowledge of the manufacturing workforce. This is one reason that we worked with our software partner, AMPS Technologies and developed KeyCreator Analysis. Our product, KeyCreator Analysis simplifies the complexity that has long prevented the use of CAD analysis in the initial design process. We are training engineers through no cost webinars to perform simple analysis early in the design stage. This will save time and money and provide a competitive advantage to the companies that are taking advantage of this technology.
In addition to the introduction of KeyCreator Analysis, we have also embarked on a program that provides an educational version of CAD software to students free of charge.
The Manufacturing internet that the GEO CEO mentions exists in bits and pieces all over the internet today and its power is becoming more real with the advent of crowd-sourcing. You can see this power in sites like Linked-in and the site GrabCAD in which designers share their designs for free. A manufacturing community that interconnects the supply chain with all stakeholders in manufacturing is a powerful idea. It will be interesting to see how this manufacturing internet could develop.
The other Linked-in article featured today was by Hiroshi Mikitani entitled Your Brand is Your Flag .
In his article he argues that soon countries will become subordinate to companies, so companies have a great responsibility to society. This may seem like radical thinking, but international companies have a lot of influence and power today. And with this great power they need to assume responsibility for the type of society that they want to foster.
At Kubotek, we often think of our role in the world of manufacturing and society. We see our software and products as having the ability to democratize manufacturing. By offering simple and powerful CAD software and simple engineering tools, like KeyCreator Analysis, we are enabling one person or a small very company to both design and manufacture their own products. This ability will free the creativity of the individual and it will have a very dramatic impact on society. We are coming closer and closer to this reality.
Combining the thoughts of these two articles provides an interesting outlook into the future. Large and small companies can take advantage of the democratization of technology, with easier to use and simplified software. New technologies such as 3D printing and the new energy independence of America can be combined with higher skilled manufacturers--both big and small. Utilizing the power of social media and the internet can create a rebirth and transformation of manufacturing in America, as well as create the next big boom in the American and world economy. The companies and individuals that choose to play in this new manufacturing world will reap great rewards and have great responsibilities. We chose to play and embrace the future.
Thank you for reading,
Kubotek Creation Engineering Division
Today I received an email from our infamous head of training at Kubotek - "Doc Walt." He recently completed the building of his house on the Jersey Shore. He feels fortunate that his house survived and chalks it up to both providence and designing the house in KeyCreator to withstand such a storm.
Here is the story in his own words and unedited:
Neighbors House doesnt withstand Sandy's fury
There are literally hundreds of houses like this or much worse on my street and the surrounding streets at the shore.
Over half of the homes were damaged or suffered serious water and wind damage.
In some places the house is partially collapsed into the ground like this but still there.
In other cases there is debris on the lot where the house once stood.
In the worse cases even the lot and part of the street are gone with water from the bay and ocean filling the location.
So we were unbelievably lucky. I’m still a little dazed.
As Stella and I walked down the street, climbing around sinkholes and mounds of debris we met neighbors staring in disbelief at the remains of their lives.
It was like being for real in the middle of one of those disaster films.
There was also a capricious twist to the scene. Often a house would be standing intact with the ones on either side destroyed.
By a combination of unbelievably good fortune and a well-built structure our house came through without a single shingle misplaced, no siding or window damage, no structural damage.
Walt's House - Unscathed by Sandy
For reference, if you ever build a house at the seashore do what I did when I built this one: (Even some of my family and friends shook their heads at my extra precautions.)
- I designed the house in KeyCreator, evaluating each construction step.
- I added almost three tons of additional concreate cribbing and several hundred feet of ½ inch reinforcing steel bars in the cribbing to completely encircle the house piers.
- This prevented erosion of the sand around the foundation.
- All siding was installed with nails every 8 inches instead of the typical 30 inch spacing used.
- Roof shingles had 6 nails to the shingle instead of four with special drip edges along rakes and soffits.
- I added over five hundred special steel structural straps tying all rood rafters and joists to wall farming and created special truss walls in the attic to react to extreme wind loads.
- Every joist to wall tie had both Florida hurricane straps and California earthquake slip plates installed. All the extra steel only cost a few hundred dollars and three weekends of extra labor.
- So design your house with KeyCreator, spend some extra time adding reinforcements, and say a prayer.
I provide the above information with a sense of gratitude, hoping that anyone else contemplating a building project take the time to add a little extra in their efforts to prevent a future catastrophe.
Once you finish off a house structure it is virtually impossible to add these extra goodies
Our first floor is 7 feet 5 inches above mean tide level and the water surge reached exactly 7 feet, 5 inches.
We know that because when we opened the front door there was the equivalent of about three gallons of water that had just started to seep through the door sweep onto the tile floor.
I have to remove and replace the waterlogged insulation batts in the floor joist spaces of the first floor but that is a simple job compared to what could have been.
Best regards and thanks for your concern during this crisis.
Your Highness much prefers Direct Modeling to that history-based blather.
I'm planning to Tea and crumpets with that lovely Lady Sefea. She's such a smart cookie!
God Save the Queen, someone made my DynaHandle even more functional.
Yes! It is proper to design using KeyCreator with your pinky extended!
Pip Pip Cherrio! A complete direct Modeler with CAM, Comparison and Analysis, I never thought I'd live to see the day!
Whoo! Did you see that royal fly-over? I am glad that they Validated those fighter jet designs using Kubotek Validation Tool.
Let them eat cake, indeed? Give them KeyCreator 2012 and let them invent!
Bully! Look at all of those pretty colors on the stress analysis! And I did it myself!
Plastic parts, parting lines, core cavity splits, KeyCreator makes it easy, And XMD automates waterlines and other features - taking the royal pain out of mold deisgn!
Using KeyCreator Direct CAD is almost as fun as a Diamond Jubilee.
Sefea (pronounced SeFEE'ah) is smart, quick and complex. She is a set of super secret equations that the not-so-evil Dr Ted Lin devised to simplify and speed the CAD Analysis process.
What does Sefea do?
She tee's up the simulation problem for the solver. So that the solver can process the simulation results more quickly and do so with less data.
How does she do it. We'll never tell, but she is the newest member in a league of new solving technology called Strain Enriched FEA (Finite Element Analysis.)
Sefea is young, only several years old in fact. You see she is much younger and more vibrant that other algorithms used by the largest and most popular analysis systems. Those algorithms are decades old and honestly could use a little work done.
And Sefea isn't haughty. She doesn't require a large and dense mesh in order to get results. In fact, she's real happy with a TET4 mesh (versus 10) and she will provide just as accurate results as those older gals, but in lightning speed.
And Sefea is frugal, she won't hog your precious memory from your workstation or laptop. So she'll give you results when those grannies have used up every last bit of memory and your laptop is gasping and choking.
Get to know Sefea, I think you might just fall in love.
Sefea - she's young, smart and fast and will get results when other's can't and she's what you will find in KeyCreator Analysis.
And for all you smart guys that want to get deep into the theory driving her, there is a White Paper thoroughly explaining all her ways.
Check it out here: Sefea White Paper.
