Trouble importing from 3D warehouse

Profile lines appear when I import any file from 3d warehouse (picture attached). I am aware of the ‘K’ keyboard shortcut but that doesn’t resolve the issue. What am I doing wrong here?

These aren’t the Back Edges you’d see by pressing K. You have Hidden Geometry turned on. Turn it off in the View menu.

You saved my bacon, thank you!

Mmmmm… bacon.


Mmm bacon? American crispy-fried/grilled or Scottish soft, just barely cooked?

I don’t see that it matters much as long as it’s bacon.
