Some a slice skips one vertex

[casperlamboo]

When slicing some times a slice skips one vertex (see attached screenshot).

• It seems that one one vertex is missing
• Surrounding layers have also one vertex missing, which is generally in the same place

• black: Intersect vertexes
• green: Intersect line
• red: the vertexes of the line

The intersection algorithm detecters that lines have a collision. When converting to path these intersection points get lost.

The model I am using (dom.stl) has a lot of bad faces, faces which vertexes are all inline. This generates a normal with length 0 (x=0 and y=0). [HYPOTHESIS] When creating a line and comes to a line of the bad face the algorithm cannot detect it has to continue the line. Instead it finishes the line leading to this behaviour.

There seems to be no hidden point and all points seems to be connected in the connect array
