I would like to find a way to give a maximum and minimum length to a stretch (or move) but without absolute values.
simplified example of my block:
I have 2 squares, of which one big on, and a smaller one within the bigger one. I want to be able to stretch both squared indefinatly (no problem there), but the big square may never become smaller than the small one, and the small one may never become bigger than the big one...
In other words: the inside square should always stay inside the bigger one, no matter the size of the squares.
The problem with this block is that I have a hatch pattern between the squares, and as soon as i stretch the small square outside (or equal) to the big square... the hatch pattern 'crashes'.
You can controll this with a reactor (lisp) but reactors can be tricky. I'll make one and you can decide if it's right for you. I'm away from autocad so you'll have to test it for me. I'll get back to you later today
