I created a face from wireframe and received the message "Problematic geometry reported for face ...". When checking the face I am told that a number of vertices have geometry check errors. Checking those vertices individually results, however, in no error.

What to do?

Make sure that there are no gaps between the vertices of your wireframe. It is possible that there are very small gaps between vertices. Zooming in might help. I know that some of the other software have equivalencing options. But I am not sure if Gambit has this.
