I think I found the problem printing the floor plan. I was using 2D/3D plug-in objects for the a 1 pc water closet, HC lav, mirror, toilet room waste receptacle and tp holder. After deleting these items from the drawing I was able to plot successfully.
I had a 2 remaining 2D/3D plug-ins remaining in the drawing; a thermostat (visible in the plot) and a 2x4 troffer (layer invisible).
This being the case, is the problem with one or more of these plug-in objects or potentially in my application of the plug-in objects? If the problem is inherent to the object(s), is there a patch?
