Re: Why do points disappear when creating multi-faces?

[Marven]

I think you might have switched on the display of “leak points only” (you can find it in the display menu at the top). If so, then only points located on the boundary of a surface will be shown, like the ones on the edges of the holes you are closing. Once a face has been added the holes are gone, and therefore the points are no longer considered “leak”.

If you have the “leak points only” option enabled in the display menu only the points which are considered leak will be drawn on screen, other points will be ignored during the drawing process.
