Help/Hints needed for patching body.

Hello. I am struggeling a bit with patching a circular surface body. The overall goal is, to merge the surface "Body2" (relating to the file attached) into the body "Body1", such that one solid object results. I first tried to use the boundary fill tool, to simply combine the two. This failed though. The reason for this beeing the surface of "Body2" not completely closed. (It has no surfaces towards the inner shaft) I thus tried patching those missing surfaces. However the lines suggested for patching did only provide for closing the complete inner hole, which is not what I wanted. I then tried some things, like creating a cylinder and merging it with the broken surface body (merge completed with an error). I attached the correspoding file to this thread. Any suggestion would be warmly welcome. Cheers.

there are probably lots of ways to do this. The design is a bit of a mess, and I'm not 100% certain I captured every single bit of design intent, but hopefully it will give you some ideas. The basic idea is to use Boundary Fill, that much is correct. Surfaces do not have to be closed to use Boundary Fill, but they must intersect completely. The other thing I did was to delete all but one pair of gear teeth, then a bunch of apparently unnecessary surfaces (some of that might be wrong - you may have to undelete some of those). Then I used Extend to make sure that the surface bodies intersected the solid, and used Boundary Fill to join to the solid, and Pattern Faces to replicate the gear teeth.

However... You might just be better off re-modeling the whole thing natively in Fusion solid. The geometry is not all that difficult. I'll leave that up to you.

Thanks alot for the quick response! Also thanks for fixing the thing and the explanation. I'll try and reproduce your steps. Probably I'll also gonna try to remodel the gear. Cheers and thanks a lot for the advice.
