Hi,

I have a simple part attached, when I extrude my sketch using "up to next"  from a plane, inside the solid (i.e. intersects the solid), it extrudes properly to all the faces in its path and not ignores them, however when I extrude the sketch from some plane outside of the solid, SW ignores all the faces in its path except the one on the back.

I know it's not a bug, and it has something to do with how "up to next" works, but I can't think of any good explanation that convince me. So my problem is not modeling it the way I want, just want to know what exactly is the reason for this.

Thanks,

Vahid,
