Creating Threads - Boolean Operation Does Not Generate Valid Geometry

john_wolter_personal

I have tried to create threads on a part using the technique in this Tech Tip: https://www.onshape.com/cad-blog/tech-tip-creating-a-thread

However, when I try it I'm getting an error, typically "Boolean Operation Does Not Generate Valid Geometry"

Here's an example https://cad.onshape.com/documents/77dca40eeab496b22cfbef5b/w/80f78b161cc5c6dbfa2039d4/e/b71cda6c2eeb68ec1dc8d1c0

Your profile sketch (Sketch 2) is at a slight angle (it is rotated), and as you can see it is blue, meaning it isn't fully constrained. Add a vertical constraint to the vertical (which currently isn't fully vertical) part of the triangle, and you're set.

Thanks, øyvind_kaurstad, I didn't notice the blue.  I had a feeling it was something simple...
