I was trying to create a solid from the attached file. i have two planar curves (red) and intersecting lines (purple). The upper planar curve is two semi-ellipses joined by two lines. The bottom curve is a circle.
If I do a a sweep2 and cap, the opening at the circle will not close.
If I do a networksrf with all the curves, cap creates a solid.
This seemed like odd behavior so I share.
