Thank you for your honest feedback. As for other systems that can also emulate this process, there are none. However, bringing different packages together from various third parties may at least approach the process.

The good news is that more systems are at least providing 3D GD&T and companies like Adobe are chiming in with providing extended viewer capability to provide downstream value in the 3D GD&T without having to use CAD.

But when it comes to tolerance analysis, I think 3D is the only way to go and from what I have seen, VisVSA is simply in the lead.

I also appreciate your candor with regard to my writing style. I can't please everyone and you are right I did find an instance of "to" being incorrectly used. Sorry about that. Btw- sentance is spelled sentence. lol and again thanks!
