[Ma...] Posted June 10 Share Posted June 10 I have a round part with a plane close to the top. Datum B is the plane. Datum A is the OD. Base alignment is the plane as Spatial and Z Origin, OD is X and Y origin, and there is a small slot in the top plane the is perpendicular to the plan, but rotated 15 degrees. This slot is my rotation in the base alignment. On top of the -B- plane is a scrollwork like feature with a profile to ABC. There is also a profile for the scrollwork. This scroll work walls are basically perpendicular to the plane -B-. How do I set up the fitting options for the scroll work freeform in order for the profile to just A and B reads correctly. I think I want to allow rotation and X and Y and that's it (Looking for advice to understand)? When you check the box is that allowing rotation or stopping it?

[Ma...] Posted Thursday at 05:07 AM Share Posted Thursday at 05:07 AM What is checked, then it's used. If there is a profile callout with datums, then you have to look what is free. If you have only A and B in callout's datum, then you allow only rotation - nothing more. If you have a newer Calypso, then use GD&T and fill only used datums - rotation will be automatically added.

[Ma...] Posted Thursday at 01:14 PM Author Share Posted Thursday at 01:14 PM I thought it was just rotation around z. This is version 2018. So I probably have to allow rotation in the freeform. Thanks. Link to comment Share on other sites More sharing options...
[Ma...] Posted 5 hours ago Author Share Posted 5 hours ago Please sign in to view this quote. I made two freeform surfaces that use the same feature points recalled into the freeform. One I didn't change anything. The other I allowed rotation around z. I get identical numbers from the profile to abc and profile to a and b only. I'm not sure where I went wrong. My freeform knowledge needs to get better. Link to comment Share on other sites More sharing options...
