Im learning SketchUp. And I can’t solve this problem. I have googled without success.
I made a house with SketchUp and now I want to 3D print it. So I export the STL but it is incomplete (roof is missing). I think the problem is that I did not use solids for the roof.
I am trying everything I can to fix it…
Can someone help me? Thank you in advance.
