Radial profile alignmentà.

[Tenkan]

I have a disk with some posts patterned circularly about center like a bolt circle. Although the pattern spacing (angle) is even not all the posts are there for clearance issues. Each post has a unique feature, a radius cut in the post at an angle forming a small surface feature in itself. Each of these faces must face the center of the disk. I am looking for the proper way to define this on the drawing. The OD of the disk is Datum A, the bottom surface of the disk is Datum B.

There are other features and it’s a busy part so ideally I only want to show this callout in one place in a detail view... If I use Profile of a Surface to define the face will that also orient the surface direction to the center for all of the posts?

Yes, as long as you callout datum A. You should probably specify |POS|B|A| but not knowing the specific function of the radii. I couldn't say for sure.

Im actually not good at understanding when to put the secondary DRF in front of the primary but will study more on that.

Thanks for the confirmation though, sometimes the little questions confirm the bigger understanding.
