Problem painting areas without changing color on other areas

help

#1

I am drawing a simple 2D site plan of our business. I’ve been using Sketchup for this for a year or so but have been having this problem recently. When I go to color certain areas it will randomly color areas outside the selected area. I would love some help and am willing to upload my file for someone to take a closer look at it.

Thank you in advance!

If it is 3MB or smaller you can upload it directly to a forum post using the icon that looks like a little bar with an upward arrow at the top of the post edit window. Otherwise you can put it on a file sharing site and provide a link here.

Unless the faces are not actually closed or there are multiple faces superimposed on each other, coloring one shouldn’t affect others.

Specifically I am working inside the light gray building near the top of the drawing where the dimensions are in meters.

Please let me know your thoughts.

As I orbit around your model I see a lot of color flashing (see attached animation). This “z-fighting” is a sure sign that you have multiple faces placed at exactly the same place in the model. The display system can’t determine which should be shown in the view because they are at the same place, so it flashes them as a warning.

I am trying to educate myself on faces as we speak. Is there any simple advice you can give me?

Z-fighting for sure, as @slbaumgartner pointed out.
But I’m curious how you got to draw the squares without having them to separate the large face.
It’s part of sort of a bug SketchUp is dealing with. You can heal (=separate) some square faces by drawing a diagonal and deleting it again. Not all squares can be healed this way. It would be better to redraw this part again.

Thank you…I’ll see how to clean it up.
