I have a model made in Catia (iges fileformat).
I imported it into Fusion 360, stitched the bodies together, created a sketch using lines, extruded and used split body feature.
This fails miserable, it's more like an intersect.
Creating a box, and using that to split body works exactly as expected however.
I needed a sketch because it's a large object i needed to split in two with puzzle pieces, and sketching a line is the best way to make something that just snap fits together. A 0.05-0.25mm tolerance is required for the pieces to fit together nicely.
