This is the second time I have had walls disappear in 3D views.
Here are some screenshots.
1). Wire frame view, note the walls are outlined:
2). OpenGL rendering, NO WALLS!:
3). Same view, but after copy/pasting this into a brand new file:
I have attached a sample file. Note that it is an educational file, so do not copy/paste anything from this file into one of your project files. It will put
a watermark on it. You will not have a problem otherwise.
Any help will be greatly appreciated. The solution of copy/pasting everything into
a new file is not really a workable option. I have too many viewports and sheet layers that would need to be re-built...Many, many hours of work. And then what
if it happens again?
Thanks Wes and anyone for taking on this challenge. I have quit and restarted both
VW and my computer and it still is a problem.
Thanks
