GDT Counterbored Slots

[njm789]

Hi All,

What is the proper way to tolerance counterbored slots using GDT. In my case I don't care about tight tolerance on the horizontal position of the thru slot just the spacing, though obviously the counterbore itself needs to follow the contour of the thru slot. Any advice is greatly appreciated. See picture below.

If this is for clearance, then just use a profile tolerance on each side of the through slot relative to each side. Using position for clearance like this is probably an unnecessary complication.
