I refer to the Blender built-in boolean tool described here.
I am cutting a complex surface > 30 000 facets. All the cuts are along coplanar surfaces. About 50 % of the cuts fail.
In the detail of the cut file posted, you can see that the boolean cut seems to be done, but that the tris are not removed.
What can I do to ensure that the boolean cuts do not fail, or is there an easy way to remove the tris after the cut failed?
See this large sample cut file.
