Dave,
actually it does (this seems to be a new feature in SU 6) but after a while - with too many lines overlapping - it does not really (or always) work.

Dave, indeed, a new face is created in this case - as well as if you draw a circle partly on another face. And as in this latter case, intersecting helps make the (closed) arc or the circle be "part" of the original face they are placed on.
Still when there are a lot of overlaying arcs (or circles) they don't always intersect properly and you need to use the "old, hand drawing" method to trace intersection points and turn them into endpoints.

Intersect with model will indeed eliminate the problem. Think of the intersect as cutting a hole in the larger face into which the small face just fits.

Hi all, I'm very new (second week) to SU, and have zero CAD or design knowledge, so please try to explain any answers like I'm 4 years old. I did look through a bunch of posts but didn't find the answer to my question.
I have a flat surface that I'm drawing a bunch of arcs on. However, when I get to a certain point and close an area with an arc, the flat surface goes crazy and some triangular parts disappear, some are sort of there, sort of not. When I orbit the model, the surface shimmers in or out near the area.
But when I highlight the surface, it gets those tiny blue highlight dots all over, which says to me that the surface should be there.
I've re-done the design a half dozen times, thinking that my arcs weren't on the surface (coplanar?), being careful to make sure the little things says "on face". No luck.
The only cure is not to close the offending arc, but I kinda want to.
Sorry, that's the best I can describe it.
