delete faces in gambit - also lower geometry
 

Hi,

I have created a complex set of faces in Gambit (resulting from uniting several volumes, deleting the volumes and just concidering the faces in one plane).

Now, I want to delete one of the faces for using its lines to create other faces.

Now I delete the face (lower geometry turned off) but the one line, I want to use for the other face is deleted as well!!!

What happend??
