Wondering whether your closed surface is actually closed? Here are a few tips on how to find this key information:
- Verify the number of borders in the surface’s Style Editor > Info. A closed surface will have 0 borders.
- If borders and border extremities are present on the surface, the surface is open. To make these more obvious in the camera, change their color, increase their thickness and size, or create a curve from borders.
- If you are still not sure, try to use the surface in a 3D-GIS Shell query. If the surface is not closed, the query will not be completed, and an error will be reported.
