I don't know why, but since last thursday my archicad has been very slow. And when I mean very slow, I mean archicad is taking 5 minutes to make sections to show. And if I even think about changing the photo frame, it slows down. I can make a one corner move in 4 minutes. I'm doing a solo project and it shouldn't be too big of a file. I did uninstall the 26 archicad and installed it again with the newest update. I'm using MacBook Pro 2021 with memory of 32Gt/500Gt. Is there something I'm doing wrong?
I had a similar issue once but only on certain views within one particular project. As such, this may not be a very good solution.
It turned out being an object that was very heavy to draw/redraw/move within the drawing in question. I deleted the object and replaced it with a line drawing that represented it, and all of the speed issues went away. This was a custom created object (let's say I was overly ambitious!).
Again, not sure if it will help, but I hope it does!
