Why can I see ‘shadows’ of some edges of some groups thru other groups in my model? No, x-ray is not on.
I have even tried creating a 1/32" gap between adjacent groups so they aren’t touching and STILL I can see the group. I’m building an architectural model. I’ve done this many times but not with SketchUp '22 - first time user.
I’ve tried switching between cameras, zooming extents, etc…
Why can’t stuff just bloody work when you spend a few hundred dollars on it and it’s been around forever…
Thanks for ANY help with this. I need to export to Layout and can’t have additional lines on the images.
As Aaron said, we can only guess unless you show us something to go on. My guess from what you are describing is a limitation of the graphics card and OpenGL.
Yes, you’d think with the price of graphics cards today, that maybe they could fix this sort of thing. Seems like the sort of thing you could contact Nvidia about since it’s their GPU andf drivers you’re using.
Your profile says you are using SketchUp Free (web) and 2017. Neither of those would be correct for SketchUp 2022. It also says your Mac has an Nvidia GPU which Apple hasn’t supported for years. Please update your profile as that information helps us help you.
One of the problems SketchUp has to solve is what to do when an edge and a face occupy the same space. If you check around the forum you will see reports where an edge looks less visible as you orbit, that’s an example where the problem is happening.
The solution to the problem is to artificially move all edges towards the camera. I don’t know how far they are moved, it’s a small amount, but in the case where a line behind the face is very close to the face, it may well have been brought forward enough to then appear on top of the face. The further you are away from that small gap the more likely the problem is going to happen.
So, it isn’t a z-fighting issue as such, but it’s a side effect of trying to avoid z-fighting.
You can easily see the problem in this file. Get close to the edge/face, and the edge will disappear close up, but probably still show a little for the further away part of the edge.
Very few roofs are 1/32" thick. If you model things to have a real world thickness, the problem shouldn’t happen very much.
Did you read the entire thread?! Again, they aren’t occupying the same space. They are laid over each other, with a thickness, in the exact same way you would lay materials over each other in the actual building process. It is a ‘real-world’ model.
I didn’t say that the any part of the roof was 1/32" thick - I said I separated groups, of individual materials, that would sit tightly against each other in real life, by 1/32" so that there was NO contact between the two individual groups.
It is NOT z-fighting or even close. The issue you have illustrated with that simple model is not representative of the issue I am facing at all, which is one of solid objects, with a thickness - not just a plane - not appearing to be solid.
The video that Aaron posted shows the same issue with the sheathing and rafters. Why is ‘paid for’ SU’22 allowing this to happen when the free Make doesn’t?!
It’s your old graphics card and it’s drivers. Here’s an example from SketchUp 2022 on my computer with an old but still supported graphics card with up to date graphics drivers. I have to zoom out quite a long way to get the Z-fighting to occur.
X-ray to start so you can see there’s objects behind the sheathing and siding.
NOT intuitive - ‘Preferences’ parameters are a totally different thing to ‘Profile’ or ‘Account settings’ parameters… The former is (in my experience) how you want something to behave or appear, the other simple data…
