Trying to resolve moving part to origin and getting dimension corrected

Thanks so much!

it is 18.81 mm to the radius with a step down thickness of 1.89mm which is half the channel thickness from land to surface. the other half continues 21.80 is a cavity an is where the pin head stops.

Sounds good!

I'm confused what you are trying to do. Can you draw the pin in position? Or sketch on a piece of paper and take a photo.

Personally I'd model the pin head as a separate solid and then "boolean subtract" it from your part.
