When opening .dgnlib files to edit levels, text styles, or whatever, I am often confronted with the WorkSet Alert dialog.
Since dgnlibs will be used by multiple WorkSets I usually like to have mine not branded - No WorkSet. Sometimes, however, I'll be in a hurry and just click the Open button on the alert dialog, and brand the dgnlib to my active WorkSet. So far I have not encountered any adverse effects of branding vs. not branding dgnlibs.
Is there anything good or bad about branding your dgnlibs, not branding your dgnlib to a WorkSpace, or doesn't make any difference?
