Updating dynamic blocks in nested blocks.

I have a dynamic block called BEAM with a parameter called LENGTH. 80% of the time it is nested with frames and row spacer blocks in a block called RACK TYPE (i.e. RACK TYPE A, RACK TYPE B, RACK TYPE C, ...) At aisle ends or near obstructions I'll insert the block BEAM un-nested.

Any way to select the nested and un-nested BEAM blocks at the same time?

I am trying to update the parameter LENGTH for all the BEAM's at one time.

You could do it with some code, but not in basic AutoCAD.

Any canned (already) developed code I could try? Is there a simple place to start?

Making the changes I previously described represents the majority of the work going from project to project.

Nothing as specific as that. In addition to selecting all primary level blocks, you'd have to step through all blocks looking for that particular block.

Thanks for your insight. Maybe I'll keep to manually opening the RACK TYPE blocks and updating BEAM.
