Error Messages on Model Load + Dimension Tool Not Detecting Edges

[stacy11]

When I open this 3D Warehouse model, I get a ton of error messages like ‘CLoop for CFace is oriented wrong - fixed,’ but the issue persists. Also, I can’t measure the blocks because the dimension tool doesn’t detect the edges. Any idea what’s causing this and how to fix it?

Here’s the model: URL

Typical of geometry created in another application. I fixed the incorrect tag usage and purged unused content.

I also exploded the top level component. As for the incorrectly oriented loops I wouldn’t worry about it. That shouldn’t create a problem for you anyway.
