Error splitting body

[Anonymous]

I am working on this model:
https://a360.co/3hBwa2t

I am attempting to split it but depending on how I attempt it, I get different errors that I am not able to get around.  If I attempt to split on the split plane I've added, I get:

Error: No intersection between target(s) and split tool.

If I attempt to create a body to cut the other half of the body, I get this error:

Error:   There was a problem combining geometry together.
    If attempting a Join/Cut/Intersect, try to ensure that the bodies have a clear overlap (problems can occur where faces and edges are nearly coincident).

I've run the Validate command on it and it doesn't fine any issues.  I'm afraid I've exhausted my Fusion 360 knowledge which isn't all that deep to begin with. 

Any help would be greatly appreciated!

Can see it, but can't download it, for review.

Ah, I didn't realize setting it to downloadable is a subscription feature.  So, here's the file.  Sorry about that!

that error is misleading.  I think it is kind of a default error message when we can't figure out what is really wrong with the operation.  I kind of suspected what the problem was, and my experiment proved it.  Fusion seems to stumble at times with splitting a symmetric body like that. I will create a bug for this, but here is a sort of a workaround:  It depends how accurate you need to be with this operation.  I found that if I moved the cutting surface by even .1 mm, the split works.  See the screencast. 

[edit] the Fusion bug is FUS-76691

That seems to have done it!  I think I can deal with the minor offset on the split for now!

Thank you!

[edit] oh, is there a way for the general public go follow Fusion 360 bugs?
