Elements will sometimes show up as faint images through surfaces, even if the top surface has thickness. The faint background images often appear and reappear as you zoom in or out. Is there a way to insure that - for instance - the outline of wall studs don’t transmit through drywall as you view an animation?
What you are seeing is an OpenGL limitation As the distance between edges relative to the distance to the camera becomes closer, the graphics card starts to display those edges behind the surface. The studs behind the sheetrock in your example. The solution is to use tags to control the visibility of objects. Turn off the visibility of the tag for the studs when you only want to see the sheetrock. Or turn off the trusses when you only want to see the sheathing or the shingles.

Thank you! I will give that a try…

Hello, I don´t know how to call this, ghost lines and ghost surfaces? I can make a solid component, I do my stuff from scratch, suddenly my models will star doing weird stuff, ghost lines will appear, surfaces over surfaces… hard to explain, here is a picture
@skepticdad, the dotted and dashed lines shown in your model are hidden and softened edges. SketchUp will create those to maintain faces when vertices get slightly out of plane.
Hard to tell from a screenshot what you did to make that happen, though.
Hi Dave,
hard to describe, I can’t make a solid component, suddenly the model will make multiple faces on one square face, if I double click on the model, that’s what I see, it’s not a clean model but a mess, I can’t pull or push on a wall because it will only grab one segment, in this picture I try to pull the whole side, and it’s a square, but it only grabs one segment … I can’t make a solid
You need to attach your model.
This is my model, if I move anything on the model, try tu push or pull I cant, there are no more flat surfaces, thank you

As I wrote earlier, the faces are being triangulated because endpoints are not remaining planar in your modeling process.
How large is this thing? You might find it easier to model with units set to metters and treat millimeters or inches as meters.
Very likely your work flow is creating many of your problems.
it is a 3D model, I use mm, this is not the only one, on many of my models I get this, and is is difficult to clean once It starts happening, .
I know it’s a 3D model. I’m suggesting that you should model it in meters instead of millimeters. You can either set the import units for the .stl to millimeters or, if the slicer won’t let you do that, scale down before exporting the .stl.
Here is one of numerous problem areas.
Working on this at a larger scale will make these sorts of things easier to prevent or fix.

I’m curious, you say you do you things from scratch but It looks like something that has been imported from other software. I’m not criticizing just trying to work out what it is in your workflow that is wrong.

I have no idea where this come form, I use solid inspector to check the model, I need to use mm because I do 3D printing, out of nothing It will star doing this and sometimes I need to start from scratch again. if you try tu pus pull on the wall, you will see my problem
So you have a random poorly made model that you want us to tell you how to fix.
I’m happy to teach you how to use sketchup.
Actually no. As Dave says you should be modeling in meters to avoid making tiny faces. Your slicer (which do you use?) will convert M to mm for you. We all 3D print, we all model in meters.
It sounds like you are making the errors as you model. If you are moving vertices or connected faces of your model, the adjacent faces will get dragged around and triangulated this is how SketchUp works.
You say you are modeling this from scratch? These look like import artifacts from another format.

I don’t need Push/Pull on a wall to see your problems. They are obvious throughout the model.
No.
It’s not doing this “out of nothing”. There is a reason for it.

Yes I know how to use it, sometimes my models ar a bit complex many curves have to be very precise, and that’s where I get my problems, on this small model, it is an LED support, if I try to make a flat surface and celan up the lines, the whole side will disappear and difficult to edit[3d.skp|attachment]

That is nothing more than not understanding the underlying geometry of what you are working with. And as has been mentioned several times, scale up.

That may be the problem, I use mm, yes, the stuff I do is from scratch, specific things for my mechanisms, the slicer is not the problem, I use repetierhost and prusa, my problem is difficult to edit the parts once they start doing this, as I said before, I will get tis error to often on small parts… Will star working in meters, thank you
