Can't split solid with surface stitched

[smleetr5D7YX]

Hello, I'm working the field of reducers.

Nowadays, I'm trying to design reducer in inventor.

I would like to inquire because an error occurred while designing using split in Inventor.

There was no problem with other models, but a problem occurred with that model and the cause cannot be found.

I would be very grateful if you could check the file and let me know the problem.

Thanks.

Hi

The model has no body. Surfaces can be divided using the Split tool.
