Block has two different assoc 2 names

[tcorey]

I don't get it.

I have a block, the name is "P-Slope Arrow" but this is only sometimes the answer I get back when I (cdr (assoc 2 theblock)). I can take two blocks, look at the properties window in AutoCAD. Both will be P-Slope Arrow. If I (cdr (assoc 2....)) both of them, one might come back "P-Slope Arrow" and the other might come back "*U525" or some other *U###.

Can someone enlighten me as to what is going on and how to drill down to the common name when AutoCAD returns *U###?

Thanks,

Tim

Hi Tim,

Dynamic block???

Try to get the 'effectivename property as a vla object...

Hope this helps,
Henrique

An altered extract from another routine of mine that gets the effective name from a dynamic Block, but the ordinary name from an ordinary Block, and puts it into the 'name' variable:

        (setq
          bobj (vlax-ename->vla-object (car (entsel "\nSelect Block: ")))
          name
            (if (vlax-property-available-p bobj 'effectivename)
              (vla-get-EffectiveName bobj)
              (vla-get-Name bobj)
            ); if & old
        ); setq

Thank you, gentlemen. That solves my issue.

Best wishes to you both,

Tim
