I am trying to cut (bisect) an imported mesh, but I think I am doing something wrong or the mesh is just broken. Video: https://youtu.be/mqQdibQdQhA

What do I need to do to fix this?

  • $\begingroup$ does it work if you select all in Edit mode? $\endgroup$

You have split faces, select all in Edit mode and merge by distance, with enough Merge Distance in the Operator box, then use the bisect tool, it will work fine.

  • $\begingroup$ i cannot seem to find "merge by distance" in the merge menu. $\endgroup$ Sep 5, 2021 at 18:41
  • $\begingroup$ Select all in Edit mode and press M > Merge by Distance (bottom of the pop-up window) $\endgroup$
