I’m having some issues with some form of hidden object that is obscuring part of my drawing, see attached. I’ve read up as far as I can but just can’t understand what’s going on. I’ve always only used SketchUp for simple 2D drawings like this one (using SketchUp Pro 2017), and never had this issue. This drawing was a .dwg import, so it’s probably some layer/component or whatever that came with the original file. Another thing is that many times when I shade a shape/area, it either doesn’t like it the first time round or sometimes shades it a different colour! It’s driving me a bit potty, especially as I suspect the resolution will be very simple. Any help appreciated!
Thanks - did a bit of a search on Z-fighting and simply moving the drawing to another area resolved it mostly (although the first couple of times the ghosts appeared in another part of the drawing…). I’ve moved it all again and I think that’s helping now. But how do we get rid of those other things causing this? It’s like they are ghosts where I can’t delete or find out properties of them…
As a guess im going with it not being z-fighting as such.
Possibly a graphics issue caused by the origin of the imported dwg being too far away from the sketchup origin.

Do not assign tags to raw geometry until you learn how to use them. It is advisable to leave geometry untagged and only tag groups and components.
Brilliant guys, thanks - I’ll dive into this! What had actually solved it today was to just cut and paste the drawings into a clean file and no probs after. I’ll play around with the corrupted file as well to understand it better.
