I tried cutting using Basiccmdlineapp.exe and encountered a similar problem. Attached are the relevant information and cutting documents data.zip 。

Hi @monkeygame

MCUT currently offers a rather simple implementation of MC_CONNECTED_COMPONENT_DATA_FACE_TRIANGULATION, which can sometimes produce degenerate triangles ('degenerate' in the sense of having zero area).

This will be addressed in due course with a more robust triangulation routine that also produces higher quality faces.

Consider using MC_CONNECTED_COMPONENT_DATA_FACE for now. Note however, that this is not a solution but a possible workaround for the time being.

I will leave this issue open until proper triangulation is implemented.

Thanks for your reply, very nice work, come on

This bug is now resolved in the latest release.
