LMAO, like that idiot over on the SketchUp forum talking about how BAD AutoCAD is an then....right out of his own mouth.....

Ok, but Autocad is not a competitor with a program like Revit for instance. So why would a Revit user bash Autocad because it can't do the things that Revit can do? It's not supposed to be like Revit. It's not even in the same ballpark. And anyway, this guy is not a Revit user. He's coming from Datacad and he has admitted that he hasn't used Autocad since 2000, but rather than ask for help, he signed up just to complain, and that's my biggest problem with his post. I don't care if people don't like Autocad. I couldn't care less. But when someone has little to no experience with the program and they sign up for no other reason than to complain and post negative comments, that's not cool. This is a help forum, not the complaint department.

Since the property of being an external reference or an anonymous block are all encoded by DXF group 70, there needn't be as many tests to obtain a list of block names which are not external references (or dependent on external references), or anonymous blocks - I believe the following will suffice: (defun getblocks ( / d l ) (while (setq d (tblnext "block" (not d))) (if (zerop (logand 21 (cdr (assoc 70 d)))) (setq l (cons (cdr (assoc 2 d)) l)) ) ) (reverse l) ) Here: bit 1 tests for anonymity bit 4 tests for an external reference bit 16 tests for dependence on an external reference
