SolidWorks and Motoczysz ...
Not sure if a repost or not.
Even for marketing/testimonial use.
Cool to watch!
That nicely shows how important 3D modeling is to a design process. I use Solidworks every day and would not be able to work nearly as quickly and accurately if I had to work everything out with paper and physical models.
I wish the video showed some of their workflow. I am always interested to learn how others build complicated models.
