Good idea. I was able to correct for this .skp file. I first had the same blanking when I selected “View/Section Planes” or “View/section cuts”. I believe I was finally able to see all the sections when I selected “Edit/Unhide/All”. Then I could select and delete.
Ive had an ongoing problem as I seem to be inadvertently creating sections in many of my models? And often they are diagonal sections? To my knowledge, I never intentionally created a section in this model?
When I have noticed these section problems I have had been challenged trying to understand how to view and erase sections.
I had researched viewing and deleting sections and found little documentation and few FAQ’s. Noted the Sketchup Help Center article on Sections “Slicing a Model to Peer Inside” doesn’t address these items. Is there a good reference available?
BTW am a true fan of your efforts and have found many solutions from your responses. Thanks again.
