NETWORK CURVES non pinch surface

Hi Alex, the top and bottom surfaces of your cutting object there are extremely mangled surfaces with control points shooting far far away into space. The control points are so far off that they won't display in MoI in the normal display but if you do select all they will:





Many operations will be unpredictable on surfaces like that.

Was this maybe created by projective flow but with a base surface that had many areas that did not connect to the target object? Projective flow shoots out rays along the base surface and if those rays do not hit any piece of the target object it can make for bad results.

You'd probably need to do the projective flow with a smaller base plane, not one that sticks out past the target object along the outer areas.
