While editing a floor plan I'm noticing that group of walls are missing. no changes to the layers have been made. If I open the same file in TrueView the drawing is complete...
Any ideas what might be causing this matter??
Are you using a vertical product or add-on? And what are the specs of your PC, graphics card and operating system?
I have experienced this SEVERAL times. Typically it is just the "display order". I just highlight the item in the way > right click > select "display order" > select "send to back".
I hope this helps!
