Position of angled slots

[[Ze...]]

Hi all,

I wanted to pick your brain on how you deal with angled slotted features. It's common on older drawings without GD&T to notate angled feature locations with angle dimensions coming from the center of the part. It's implied that you would origin to the center of the part, create a line/plane to the feature, and dimension that based on the block/feature angle tolerances. This bugs me, because technically an angle controls orientation but not location. You get a pie shaped tolerance zone by doing it this way, where the further from the center you are the greater the location deviation can be. This crosses over into hole patterns dimensioned this way, as well. 

So how would you convert this to GD&T? My first instinct is to use profile and call it a day. It's not a feature of size, similar to a cone, so I can't use position. Or can I? 

Here's a simple example to show what I'm talking about. It would be great to get some insight into how other people deal with this type of feature using GD&T.

Not my area of expertise, but I think you could create an intersection between the centerline of the slot and the outer diameter (or any constructed one), then use a polar true position based on radius and angle.
