As you are defining the dimension loop, if there are size features that should be included, you can select size dimensions that are either connected to or centered on the current dimension loop endpoint. When you select a size dimension, you will be prompted to specify whether the related geometry is a hole or a pin.

There may be a set of identical size features driven by a single driving size dimension, such as in a pattern of features or in a sketch with equality relations. When this occurs, the driving size dimension appears as an option whenever one of the driven size dimensions is a valid choice for the next dimension in the analysis. The driving size dimension can be included in the analysis multiple times, if needed.
