Cannot edit block in place.
The attached file is a copy/paste of ONLY lines, ellipses, circles and arcs.
I'd like to create an *editable block; I can create the block (also included in the file), but when I attempt to refedit I get this error:
Command: REFEDIT
Errors found in references to other objects:
** Application reference missing: GENIUS_GENBH_13, to AcDbLinetypeTableRecord.
** Application reference missing: GENIUS_GENOREF_13, to AcDbLinetypeTableRecord.
Could someone please tell me what is going on here?
From what I can tell this has been a problem for at least TEN YEARS.
Is there ANYTHING I can do aside from just REDRAWING line-for-line?
Thanks.
