Working with files from Alias...?

I'm wondering whether anyone has any relevant experience, working with files exported out of Autodesk Alias?
I'm working on a project now, and the designer is creating a product using Alias. I've asked that he export a stitched STEP file, but it just doesn't seem to behave as well inside MOI as I would hope. The initial surface quality is poor, although, I've been able to stitch a number of those problem seams. But I'm also having difficulties with adding chamfers (for instance) to some seemingly clean edges. They just don't take. I'll post a sample scene shortly, but I wanted to get a quick post here, to see if there are any immediate suggestions for working with Alias model files.

Thanks!
