This I do not know.
I'll have to research this.
Thank you, irneb.
I think it might error, but that's circumventable also
I ran it on a drawing with xrefs and it never errored or did anything strange to the drawing. I'd still like to do a data dump to make sure. TBH, I was under the impression that an xref wouldn't bring in all it's block definitions.
I'll play with the dynamic blocks (we use very few). This was more about fixing a bunch of storm/sewer structure blocks.
It's a huge help. As always, I appreciate your council and time.
Annotative blocks do not create anonymous blocks.
Wait do you mean saving drawing with annotative blocks to 2007 or earlier?
I didn't think so. Thank you. And no, I'm not saving anything down. Hell, with my new machine, I only have access to c3d 2013.
