Why Manufacturing Should Throw Away their History-Based CAD Modeler

Posted by Scott Sweeney on Fri, Jun 03, 2011

History-based modelers: SolidWorks, Inventor, ProE, NX are the wrong CAD tools for manufacturing.

Products are rarely designed in CAD with manufacturing in mind.Thus models often have to be re-created in Manufacturing.  This not only wastes time but introduces the possibility of more errors in the process of re-creating the model. So what seemed like a logical choice, particularly for the IT department - one system within the entire organization - actually has increased complexity and cost and reduced quality in the organization.

One could argue that history-based modelers are also the wrong tool for design conceptualization or creation, but we will leave that to another blog.

Another major step in the manufacturing process is the creation of new designs to support the manufacturing process. Tools, dies and molds are often one-offs - using a history-based modeler requires you to set up relationships and constraints to build this one-of-a-kind model.  This wastes much time and limits creativity. Many designers currently using a history-based modeler to do this work may will disagree with this.  But, I believe that this is simply because they do not understand the concept and simplicity of Direct Modeling.

History-based modelers do not support sharing and collaboration in the supply chain.  History-based modelers do not import non-native geometry that can be easily edited and changed for manufacturing.  If the geometry is imported, it is generally not very useful.  Once again, manufacturers are ofter forced to recreate models using their own history-based CAD system, wasting time and introducing the possibility of errors.

Direct modelers can import and use geometry as if it were created within their own system.  This allows manufacturers to accept any type of data from anywhere in the supply chain.  This reduces cost, saves time and increases quality

So before getting hoodwinked into tossing out the 2D CAD system that you are now using (to redraw your 3D CAD Models) and buying the history based system that your engineers are using, consider using a Direct Modeler. What?! you have already bought the History-based Modeler for Manufacturing and you are wondering why they are not using it. Throw It Out! and get them a Direct Modeling solution.

Ever feel caged in or locked in when you are trying to design or edit in your history-based CAD program (SolidWorks/Inventor/ProE/UG...)?

Computer Aided Design means the computer is aiding your ability to design and make changes, right?

So often, History-based modelers want to lock you in early to a design concept.  They give it a name, design intent.  But, what if you want to develop the intent as you are designing?  Shouldn't you be able to change your mind and try different designs to maximimize the quality and minimize the cost of manufacturing the parts or product?

If you are used to History based CAD, it may be difficult to understand how to use a History-Free modeler.  You might feel that it just not worth understanding or learning a new (and easier) way.  But these new design tools are worth a look!

One employee detailed her journey from Solidworks to KeyCreator in a recent blog.   You may want to read her revelations as she unlearned the history-based paradigms that were shattered as she learned to use KeyCreator Direct (History-Free) CAD.

With a history free modeler, you can start your design however you like, and with KeyCreator, the ability to use smart tools like the Dynahandle(TM) to cut and paste features (and various other things) continues to work even as your model gets complex.  

The market is now learning about all of the advantages of History-Free modeling.  History-based modelers are now introducing elements of direct modeling into their history-based modeler, but these tools are limited at best.  To enjoy the true freedom of Direct Modeling, a history-free modeler is essential.

We are convinced that many designers and engineers in the supply chain are using the wrong modeler.  Life could be so much easier for them. So, for a limited time, we are offering an incredible Competitive Upgrade program.  Upgrade your history based modeler, any version, any company (SolidWorks, Inventor, ProE, UG, NX...) and receive KeyCreator, complete, with history-free modeling, many translators, including native Solidworks and Inventor translators (and many others), for only $2,200.  This is not a lease. This is a full perpetual license of KeyCreator.  Want to learn more?  Click on  Upgrade your History-based CAD.
