Split Body fails

It was successful until last November.

The surface you are using for the split body fails to intersect the body completely. If you move the surface body, into the solid body by a distance of 0.02mm it will fully intersect and the operation will complete. I cannot comment on the fact you said it worked before. Model is attached.

Thank you John,

Yes just by moving Body323 ±0.02mm in Z direction, the command success. But +0.02 or -0.02 mm both work.

Why? I feel this is a bug. The current modeling kernel fails to handle the common surface of Body323 and Stitched.

For example, you can successfully split Body1 by Body5 in the attached file.

This example clearly has a true overlap of the splitting body with the model. In the other example it is partial in many places. You may be right but I believe it to be a marginal call as to be a application problem.

If I don't have the existing design, the bug is not a big problem.

But I have the design which raises the error just by running Compute All command.

It means I cannot modify the timeline of the design.

Fusion 360 doesn't allow to use old version, so the bug is serious.
