I want to taper a square 30 by 30 to a trapeze with base 20 and top dimension 40, height 30.
What I do is:
I select the object to taper
I point the start and the end of taper axis
(Copy=No Rigid=No Flat=Yes Infinite=Yes PreserveStructure=No)
I type start distance 20, end distance 40
Why on earth do I get 30 and 60 instead?
If I set 10 instead of 20, I laso get 30 (the initial dimension).
