Q - question

Where do the blocks like 'A$C344D62E1' come from?

A - answer These are randomly named blocks created during the DROPGEOM operation (using "Paste as Block" with the right-mouse-dragging of drawing objects). See Tip 3939. Blocks with names starting with "A$" are also created when using copy/paste geometry (PASTEBLOCK) inside a DWG or between DWGs. These are not "anonymous" blocks (compare with *U-blocks).

You can rename the blocks to more descriptive names.

You may need to explode such blocks with:

_EXPLODE (ssget "_X" '((0 . "INSERT")(2 . "A$*")))
