angle 70°

[[Fe...]]

Good evening, how can I calculate this angle? I created a theoretical plane by placing it at the intersection, but it gives me a result of 60°

Any help is appreciated,

thank you

Check the complementary angle (20)°, to see if there is something wrong with your theoretical plane or if the angle is 60°.

It's turned part, so i would scan just lines in part axis ( as viewed )

For small lines i usually do points instead of scan.
If curve is available, then you can scan curve - make alignment from bestfit of curve to have correct data for small lines.
