Hello:
Several years ago I was using AutoCAD ( I think it was 2.6 and still only DOS-based) to design model airplanes. One of the most valuable features was the possibility to assign different specific weight or mass properties (densities) to any solid and have AutoCAD calculate the combined center of gravity.
Recently a friend of mine asked me to assist him with a similar design task. He is usingAutoCAD R14. To my surprise I found that there are plenty of materials you can assign to a solid but that concerns only its looks after rendering and does not include any physical properties.
The explanation in the Help-File "Because AutoCAD uses a density of one, mass and volume have the same value." is in my opinion rather an insult to ones intelligence. Why are they both seperately displayed ???
Am I missing something ? Is there a possibillity to get that most valuable feature back.
I would be grateful for any help.
