Title: vla-addleader but with a null value
Post by: hendie on December 11, 2003, 05:48:01 AM
I'm not sure if I've asked this before but...

in the help file under vla-addleader it states:
Quote
You can also create leaders that are not associated to a particular object. To do this, simply input a NULL object as the annotation.

I've tried and tried but can't seem to be able to do this. Everything I've tried gets a response of:
Quote
; error: ActiveX Server returned an error: Parameter not optional

can anyone give me some clues as to go about this ? I've done a few searches and every example I can find uses mtext but none use the Null object

There is no representation of a NULL object in VLisp. I did some tests as a result of the exact same question posted elsewhere and found a text somewhere (sorry, can't remember where, maybe the knowledge base?) that states it can't be done.

Only workaround that I found is to give it an MTEXT object and then delete the MTEXT afterwards.

thanks Stig, I knew you would come back with a quick response.
I had thought of the add and delete method but was hoping that it was possible somehow.
onwards and upwards !
