Bob Ross and The Joy of 3D Direct Modeling

Posted by John McCullough on Thu, Aug 26, 2010

John "Bob Ross" McCulloughWe've had some fun here recently in Marlborough creating a short parody of one of my favorite 'how-to' TV show hosts - Bob Ross. Check it out here - [The Joy of 3D Direct Modeling]. 

Bob had a 30-minute landscape painting show on PBS for over a decade. If you missed it, well, that's your loss. If you are interested in picking up a copy of some classic episodes check here [BOB ROSS JOY OF PAINTING SERIES: 3-HOUR WORKSHOP DVD]. He did some amazing stuff with a fan brush and titanium white. Bob's pleasant demeanor and positive commentary, which often came across as dry humor, was what made the show special. That and his hair of course.

While researching some Bob Ross quotes to use as part of the script I was reminded why I liked him. He made encouraging comments about learning painting which demonstrated a strong belief in the potential of everyone. He encouraged his students to paint from their imaginations and to not limit themselves to rigid formulas. He went on to explain how we each have a different set of eyes and all see the world differently.

I hear a lot of Bob's philosophy in the Kubotek KeyCreator 3D direct modeling philosophy. Commonly used parametric modeling software locks models to initial ideas and limits the ability to experiment with changes. The features lock models to the thought process of the initial design engineer without allowing the eyes of others to see the model as a different set of features. In contrast, 3D direct modeling is conceptually simpler and easier for new users to open up to 3D modeling. 3D modeling can be easy and fun for everyone.

How 3D direct modeling and the way I clean my house are related.

Posted by John Agoglia on Fri, Feb 26, 2010

Yes.  That’s right.  I clean house the way designers and CAD jocks use KeyCreator 3D direct modeling.  How, you say, can these two things be related?  Let me explain…

When I get in the mood to clean, you better look out.  There is a flurry of dusting, sweeping, mopping, wiping, consolidating, throwing out and organizing.  But I’ll be the first to admit.  Don’t expect any of this is a logical, progressive, abc-123 order.  It drives my husband insane.  I think it even drives my pets insane, but at least they can’t vocalize it. 

I’ll be in the middle of sweeping the floor when I see a stack of junk mail on the counter—and two on the table.  Ah!  So, before I forget what I want to do (which is to clean up these masses of paper), I leave a pile of dust bunnies in the middle of the floor.  After all, I know I won’t just keep walking past that pile when I’m done with the junk mail.  It’s sort of like my sticky note to myself—when you’re done with the mail, finish sweeping. 

This process goes on for what probably seems like the entire day to my husband.  He walks into rooms filled with piles of this or that, doors ajar and me mysteriously no where in sight.  Why?  Because I found something else I wanted tackle right away, before I forget…then I can get back to what I was doing which is obviously in mid-process.

I’m pretty sure this isn’t the cleaning process Martha Stewart advises.  I think most tips tell you to start at the top and work you way to the bottom.  Go in order.  Don’t stray or you’ll be less productive.  Or worse, you’ll end up with a house in more disarray than before you started!

Yeah, right.

I’m also sure this is how some CAD software advises you to design.  Go in order.  Start at the top and work you way down.  You have to do A and B to get to C. 

But what if that isn’t how you think?  What if you want to start at the top, work you way down, go back to the middle, lather, rinse, repeat?  Are you expected to know everything you uncover before you even get started?  No one expects to find jelly smeared to the bottom of the chair while you’re mopping.  But sometimes you do, so you stop and clean it up before you get back to the obvious task at hand. 

That’s why 3D direct modeling works so well.  You don’t have to go in order.  You hum along until you find something else you need or want to attend to.  Then get back to where you were and keep going.  With 3D direct modeling, you don’t have to worry about redoing all your work just because you made one small change.  You make the change and keep going.  Or in my case, you mop the floor, clean up the jelly, and keep going without worrying about leaving footprints all over a wet floor.

A blast from the (Aerospace) past...

Posted by John Agoglia on Fri, Oct 02, 2009
B-17 Flying FortressTwo exciting things happened this week (exciting to those of us who have a love for old aircraft). A B-17 flew directly over my house on Tuesday night! I stood in my front yard and marveled at the sight and listened to that wonderful roar of the engines...it couldn't get any better. But it did. On Wednesday afternoon, a B-24 flew over our office building. We're located on the top floor of a building situated on top of a hill. I could watch the bomber until my eyes were simply too strained to follow it. To see the planes on the ground is one thing, but to see them in the air is fantastic! The aircraft were part of a Wings of Freedom tour that flies the historic planes into local airfields. In addition to the B-17 and the B-24, a P-51 Mustang was also part of the tour. Unfortunately, I didn't get to see that one in flight. But trust me, I kept looking for it!

Enter a little factoid I discovered when doing some web searches on the planes (you know, because I just had to see more). Did you know the P-51 was designed and built AND airborne in 117 days. (Thanks to Wikipedia for that info.) 117 days! 117 days? Can you imagine doing that today? Think you could? Oh, and by the way, you wouldn't be able to use CAD to create your drawings. And forget about using 3D CAD models.


So that brings me to this thought. Even though today's aircraft are so much more complicated, why does it take so long to get these state of the art programs into production? Especially when so many sophisticated tools exist and are available to the engineers of today. Could it be the tools are actually complicating the process? Do the aerospace OEMs need simpler and more flexible tools?

What do you think?

Manufacturing Outlook - Are you ready?

Posted by Mark Parent on Fri, Sep 11, 2009

 

Most recent news coming out about manufacturing points toward the fact that the economy is at its bottom. This tells me that we are probably on our way up, since current news is usually about the recent past. I'll ask the question again; has your company improved itself to handle the business that will be available in the near future. Are your engineers armed with the best software CAD tools? Have you checked out how powerful KeyCreator is as a CAD tool?
The manufacturing sector should begin to rebound in 2010, with MAPI forecasting 14 of 24 industries to show gains, led by housing starts with a 59% rebound from historically low levels. The turnaround should continue in 2011 with growth likely in all 24 industries, including seven by double digits, led by housing starts at 40% and industrial machinery at 25%.
