Methods of removing Fillets from imported models

Thanks Bobby. You are correct, there is something strange with this part's topology.

Anyhow, this is what I done so far (see attached).

Bobby,

Alin's right, the part is a little funny.  Delete and patch would be my normal "go to" for this sort of thing and usually works quite well.  Like adding fillets it's mostly a matter of working out the right order to delete them. No luck on this part.

I didn't look at Alin's solution but considering the number of fillets you need to remove, and the relative simplicity of the part, I found it easier to just make a new body using the import to get the geometry (convert entity for the most part).  It leaves off all the fillets, but it's probably easier to add the ones you want to keep to the new body than remove all the others from the old one.
