Re: OneSpace vs. SolidWorks

Very nice informative post Paul.

It reminded me of when we first started using CATIA at IBM. The beginner training we received did not include any details on the underlying CSG tree and how to properly manage it. The result was what we started calling the "CSG vine". If you looked at the CSG tree for most of the models that new users created, it was basically one long branch of sequential one at a time operations. This made future modifications difficult. As I learned more about CATIA and how you should use it to create a proper CSG tree, I remember thinking that it was unfortunate that designers had to think about what CATIA was doing under the covers in order to use it effectively. When I moved to HP and started learning an early version of SolidDesigner, it was a pleasant surprise to discover that I no longer had to worry about the CSG tree.
