Hi Michael

Your last point there is a good one. I would say that one could use dimension tools to permanently measure things, or just to check things as you go.

angles, length, area, volume etc:
Could there be a kind of situation detection; like clicking on a line will give a horizontal dimension if the line is horzontal, clicking two angled lines would automaticly make a angle dimension, etc?

A solution to the "redundancy problem" is also to have a "make permanent" checkbox, so if you just want to check things as you model but don't want dimension objects you can just leave it unchecked...?

Do you have plans for some type of draft angle analysis tool?

Cheers
