Choosing the Right GD&T Tolerances

In this Question Line video, Jason answers the following question regarding locating two parts relative to each other and discusses how to choose the correct GD&T tolerances for the intended function: 

I’m working on a drawing where I need to call out the position tolerance of a shaft (.480) on a support. My goal is to define the positional tolerance based on the 1.190 dimension, specifying that at Maximum Material Condition (MMC) of this dimension, the tolerance is .010. As the support becomes smaller, I want the tolerance to increase accordingly. However, I want the part to be measured from the left side, which I’ve defined as Datum A. Can someone confirm if this approach is correct or offer any suggestions for improvement?

In this video, Jason reviews the submitted drawing, above, that shows two separate parts that will be welded together. The intent of the drawing is to locate the two parts relative to each other. He explains why the current use of the position tolerance on this drawing is incorrect and walks through three alternative ways to apply position correctly. He also presents a fourth option using profile of a surface to control the location. Throughout the discussion, Jason emphasizes the importance of choosing a GD&T method that aligns with the functional intent of the design.
