Subtracting Solids/Bodies

[Techomick]

Hello, I am using NX7.5 and need a odd surface edging. I have created a sweep that intersects with my main body and want to subract the sweep from the body. However, when I attempt to perform the subract command I recieve the error "Thru face does not intersect path of the tool. What am I doing wrong? I have atached the basic problem.

Thanks in advance,

Your swept is a sheet body that self-intersects (bad geometry). You can verify this by running Examine Geometry from the analysis menu. Secondly, the swept is a sheet body; you can't really subtract a sheet body from a solid.

You must avoid the self-intersection of the sweep, then either trim the body, or close the sweep to obtain a solid then subtract.

Here's one attempt on how this can be done. The Sweep along a guide allows sharp corners in the guide path but not self intersections. Due to technical problems I had to sweep twice. I did not remember the blend radius of the original model. Also top blends made separately to match the shape instead of radius.
