I have been working on a file for months and it’s due TODAY. This morning I went to import a DXF and the program froze. I closed and restarted it and the same thing happens. I’ve tried making a local renamed copy, I removed the software and reinstalled it, adjusting the document rendering settings… I’m completely locked out of my file.
I’ve been looking at your file and it looks like there are two viewports that need to re-render upon file load, one of which is extremely heavy - one is on page “S2.1 Wet Well Raft Slab Plan”, and the other is on page “A2.3 Headwaters Sections”.
