Why are some objects in red text all of a sudden?

I just upgraded to the latest version having not used it for a couple of months.

I had the same thin happen to me, If some of you parts were imported from step files like mine it look like there may have been import issues when bringing into the latest version.

Hi

The red color indicates some geometry parameter (curvature) exceeding some threshold. Have a look at this previous post.

Right. It was an imported step file so I’m not in control of the design of it. I suppose it doesn’t matter much as the imported step file is just a computer circuit board that I am designing a case around, it just looks messy and distracting.
