Hi all, I was wondering if you can help me. I'm trying to create a dynamic block that would change both sides of rectangle without changing is centre position/insertion point in the model space. I've manged to use the stretch actions on both sides by dragging, but only one sides changes from the centre point not both, another problem I can't get the block to work with a lookup even though ive already assigned value to each parameter in the property box. I'd appreciate any comments you may have. Thanks in advance
