Is there a way using lisp to draw transparent hatch area similar to grdraw?
I am trying to come up with a way to show the areas around a block as a transparent depending on attribute values in the block.
I current insert a block with multiple transparent hatching, but I only want to show a few of the areas, not all.
The only way I can think of is to build a block on the fly, insert and when user is done, delete the block.
See attached image of block for example.
