Please help...problem with surface color...can't figure out

kage333

Hi,

So I am fairly new to SketchUp, and have been learning a lot working on a football field project I gave myself. Everything was going fine, but then I added a triangle on the field (2D on the surface of the field) and then the color got all messed up, it looks fragmented. I can not figure out why it is doing it though. I was hoping someone might be able to tell me what I am doing wrong, I have attached a picture to show you what is happening.

Hi Kage,

This is definitely "Z-fighting" which occurs when there are two (or more) faces with different materials overlapping in the same place/space and SU cannot "decide" which one to display.

In 2D applications, there is a possibility to "bring to front" or "sand to back" or similar but since SU is supposed to work in 3D (where everything, just like in real world, has some "thickness" and nothing is in the same space as something else), there is no such thing as "stacking order".

Normally SU (especially version 7) would merge these faces unless one (or more) of them are in some other group/component (which is indeed to separate elements and prevent them from merging).

Check if you can select those white faces without selecting the green ad erase them.

Thanks so much, that seemed to do the trick. I was driving myself crazy trying to figure that out. Unfortunately I seem to have lost some of my yard lines as being a face. There must be a gap somewhere in the outline.

thanks again.

I recently had this problem, except in a much more discreet fashion. If your ever un-sure if fighting is going on, reverse the faces and that should highlight the problem if any. On the matter of the yard lines, I would make everything a component. Such as every yard line and so on. It's a memory and time saver.
