Solid.BySweep operation failed. Unable to update solid bysweep: SWEEP_FACES_INTERSECT -- A face intersects with another face in the sweep body

Sounds similar to this, i’m sorry i can’t help you further. i’m MEP and not normally dealing with solids and sweeps.

the error below is different but that might be a version change thing, it sounds like the same thing.

Sweep as solid (Self-intersecting curve problem)

I Want to do a railing like which has self intersecting paths but unfortunately i was unable to finish it the way i started in the Generic Adaptive family, so i decided to use Dynamo but i get the same Self intersecting error in both the attempt (Family and Dynamo). [2]
