FeatureCam help

My shop just purchased FeatureCam. We are finding that when we import parisolds and tey to lay toolpath on some of the models FeatureCam finds bad surfaces and will not put toolpath down. Our models have thousands of surfaces. Is anyone else having this problem?

Please post the model so that we can help with the question.
Is it a proprietary secret part?

I will see if i can get one in here for you to see.

I was not able to put this model up here. I will look for something else.

Have you tried a .step file?
