I have a quite a complex part (STEP file) that I made in fusion 360 which I need to convert to a single part / component in Solidworks.

When I import into Solidworks, I have rebuild errors. I attempted to find the problem using Tools > Evaluate > Check, and this found 3 'general faults'.

I selected 'isolate', and this showed me where the problems were but I don't know how to fix them.

The error in the dialogue box reads,

"A general geometry problem was found. If this data is imported, this problem may be due to the precision of the data from the originating system; please adjust the model/export settings in the originating system and re-import the model. If this is a SOLIDWORKS part, please report the problem to your local support representative.: generated seat B<1> (Default)"

I tried playing around the with the import settings, but it always has the same 3 'general faults' once I import it.

Any ideas? File is attached.
