Hello there!
I have a dynamic block with visibility parameters. The problem is - if I put a block into the drawing then copy it and change its visibility state file size increases. Example - put 1 block - 630kb, cloned it 5 times - 630 (it is logical, since it is the same reference). But then I changed visibility state of a single copy and here we go, it is now 1170kb! But what has changed? It is the same reference! It shouldn't change file size to my mind, why does it?
