Answer:
The elements that overlap partially or entirely in their lengths can be found using the model check for overlapping elements. To open the model check, use the menu Tools → Model Check → Overlapping Elements.
If overlapping elements are detected, they are shown in a dialog box where they are sorted by groups. In the work window, the current group is indicated by an arrow (Image 01).
The element pairs can be exported to MS Excel or created as a visibility. The visibilities created in this way (Image 02) can be quickly used to find and delete the relevant elements in the cross-section.
