A connector can contain one or more pins. Valid geometry for pin selections includes both associative and non associative points. The points you select determine whether the pins update when the geometry to which they are associated changes.
Non-associative points are arbitrary points on any face. They do not update if the geometry changes. Associative points, which update as the geometry is changed, include any one of the following:
Each pin must have a unique name. By default, each individual pin name is a sequential number starting with 1. For pin groups, you provide a prefix letter and start number, and then select the naming scheme that you need. Each pin name within a part must be unique. When the browser name changes for an individual pin, the pin name updates. The reverse is also true. To change naming for a pin group, delete the pin group and recreate it with the naming you need.
