OK, Wally, take it down a notch. @MikeWayzovski is right, one is adequate. I thought I PM’d someone about some of these, but it must have just been a draft.
The crash reports I looked at mentioned an Edge code on curves, but notable was notable in that it was on an Intel 530 (see https://en.wikichip.org/wiki/intel/hd_graphics/530). I looked at the undo stack of one, and it crashed during use of the scale tool. I don’t know if that gives anyone enough actionable information, but if you’re forced to use that video card on that version… and it were me, I would either go back to 2016 and use software rendering when I had these crashes, or I’d narrow them down to the action that I’m doing before this happens and avoid it. I know users never like to hear the words upgrade your video card, SketchUp version, etc… but that’s the real solution. For example, my somewhat dated MacBook Pro has 2 video cards, NVIDIA and Intel 4000 as the lower-power backup. When I google Intel 530 versus Intel 4000, I get this:
In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4000 Desktop are significantly better than the Intel HD i3 530. … The Graphics 4000 has 16 Shader Processing Units but the HD i3 530 does not have an entry, so the two GPUs cannot be reliably compared in this area.
This, for a card that I never turn on, in a laptop. So we’re trying to do our best with not a lot to work with on an older version of SketchUp. I hope this info helps.
