Incomplete Perimeter, Slicing with MakerBot Desktop

[oic-u3d2]

Greetings fellow designers,
I'm having an issue when I slice my .stl file and check out the preview, it looks like the slicer isn't completing the outside perimeter. If I rotate the model on my build plate and re-slice it, it'll appear in another spot. I have a feeling it has something to do with the 'Fixed Shell Starting Point' setting.. but haven't managed to solve the puzzle just yet.

Here's some background info:
3D Model: Drafted in Inventor 2015 and exported the .stl on high and medium resolution - same issue when sliced at either resolution.
Makerbot Desktop Version 3.9.0.961
.2mm layer height
3 Shells - Though I've tried anything from 2-5, doesn't seem to affect the issue.

Any ideas?
Thanks in advance!

have you tried printing a bit to see if it actually prints what it previews ?

If I rotate the model on my build plate and re-slice it, it'll appear in another spot.

sounds like possibly an issue with the previewer, rather than the file.

I was wondering if that might be the case - I'll give it a shot and see what happens.

Thanks for the suggestion! It printed out fine - must have just been a previewer issue.
