I hear ya Marinus and totally agree. I have also seen design engineers spend literally weeks to get a blend on a part when the client is chomping at the bit for parts and toolmaker sits idle. All for what, since the tool maker states the blend is not needed since it is a natural feature that is generated by the tool making process anyway.
As a product designer I have to say we are fall prey sometimes to make the parts as realistic as possible and sometimes loose site of the big picture. Thankly I keep my feet on the ground 99% of the time. But yo know you get that new release of your software with that cool feature and you just gotta try it on something. Its a case of the WOW! cool new feature but totally counter-productive.
So make enhancement requests to you software company be careful what you ask for, you just might get it.
