The Special relationship dropdown list includes a set of relationships that are specially designed to perform a unique task.
Frame to Frame. Reports a delta transform between two frames expressed in the working coordinates. This is not to be confused with the Frame Wizard relationship that drives the construction of a frame from a set of references.
Object to Object Direction. Reports the angle and mutual perpendicular distance between two objects.
Vector Group to Vector Group. Built with Sim and Gap applications in mind, this relationship requires a Points to Surface Face relationship and a corresponding vector group representing the far side of a gap. It then computes a delta vector group defining the current gap statistics and can be used for alignment.
Pipe Fitting. Pipe relationships are designed specifically for pipe alignment and cut calculations.
MP Execution. This MP serves only a single purpose which is to provide a means to identify and run an MP as part of a inspection.
