When authoring a tube and pipe iPart or a standard part, you must define the maximum engagement position ( MaxEP ). In addition to entering a precise fixed value or percentage of the nominal size, you can also specify a work plane before authoring, and then use it to define the MaxEP. The maximum engagement position is defined at the intersection of the work plane and the connection axis.
