Question:
When creating a solid, I always get the message "Boundary surfaces are not closed at edges ... " What should I do?
Answer:
This is often caused by the fact that one or more surfaces of the generated solid have double lines. In this case, the boundary surfaces of the solid are not closed and the generation has to be interrupted. In order to quickly find these lines, the program displays the corresponding message.
Solution:
You can quickly find the double lines using the feature "Tools → Model Check → Overlapping Lines". In this tool, you can also display the line pairs as an Excel list or create partial views (see the highlighted buttons in Image 02).
However, it is often not easy to delete the lines, as they are assigned to different objects. So if you delete one of the lines, you also delete a surface, for example. Therefore, you should first check all structural components to see if the lines can be deleted and change the boundary lines, if necessary.
