Non-orthogonal views make hidden geometry show through

Hi all,

I’ve been using the free version of SU for about 6 years now and have been pretty happy with it. However, I’m having an issue with the display of a new model I’ve been working on and hope someone might have a fix for my problem. I’ve attached a test case of the stripped-down model to show the basic issue…which is this: When viewed from a standard orthogonal view, in this case the left side, everything looks great. However, any time you rotate it from an orthogonal view, geometry that should be hidden begins to show through. This effect is shown in the two attached pics.

The model is of a steel panel attached to 2x6 lumber. The panel is an extruded solid that is .0142" thick…but it is a solid that should hide the lumber behind it.

I’ve been learning lots more about materials, styles, etc, but have, as yet, been unable to figure out this phenomenon. Any help would be greatly appreciated as the actual building is 30’x60’ and looks horrendous in any non-orthogonal view.

That’s typical OpenGL bleed through. See this:

Hiding the edges of the 2x6’s will prevent them from bleeding through.

Thanks for that, exactly what I needed to know!

Beat me to it!!
