Really weird issue. Archicad 16 on PC.
I've done hundreds of projects up to now with no issue.
And now when I start a new project everything is ok.
After a while as I design, I just stop seeing what I am designing. It appears only after I design it and it's there.
The wall doesn't show up as I design a wall, same with slab and almost everything.
Any ideas?
The weirdest thing is that when I start it is just fine, then after a while it does it (i think by itself).
I use dwg attachments if this has anything to do with it.
