Applying GD&T scheme to a part in assembly - Hinge bracket
Mufaddal Rasheed 
A walkthrough on application of GD&T scheme to a component part of a hinge assembly. How design intent is converted to tolerancing scheme.
When applying GD&T to a component the first step is understanding the design intent of various features. If the component is part of an assembly then the design intent is broken down from the higher level to the component.
Here are the important features of the component.
Here is one possible GD&T scheme.
The primary datum feature is the resting face with a form control of flatness applied
The centre fastening hole which is 10.2 nominal dia is the datum feature B and the other two holes with nominal size of 10.5 are Datum features C.
The Pin hole is being controlled in its position with respect to datum reference frame
Also the Datum feature B is being controlled in its perpendicularity with respect to Datum feature A which is Resting face and the two holes (nom 10.5) are being controlled in their position with respect to centre hole.
