In a dwg file,there are a lot of blocks. Some blocks is nested. How to list all the blocks in a directory form?
for example ,These are blocks: "1" "2" "3" "4" "5" "6" "7"; "7" in "6","6" "5" in "4", "4" "3" "2" in "1";
this function return value likes below:
("1" ("2" "3" ("4" ("5" ("6" ("7"))))))
How to get it?
Actually, I found a way to list all the nested blocks in a Insert.But for this ,I have no idea...
