Getting frustrated with this one. See attached. I want to stretch line 'a' along distance1 as a variable user length. Lines 'a', 'b', 'c', and 'd' should remain equal lengths. Lines 'a' and 'b' would lengthen towards the bottom of the picture 'c' and 'd' and would lengthen towards the top of picture. I've attempted to use the "equal" constraint but once the block is rotated, there are random results on the direction the lines are lengthened. I've also attempted to apply an angle restraint (60d between 'a' and 'b') to attempt to simply stretch both at the same times to no avail. Any tips or suggestions are appreciated.
Thanks,
Dan
