Identify Reference Geometry

When both the primary member and the partner member for this Association have been selected, the following window is displayed where you define details of the geometrical relationship between the two items:

The figure above shows a parallel geometrical constraint being applied to the centre line of two pumps. This example shows the case where reference geometry has been pre-defined on both Equipment elements.

The top section of the form shows the type of constraint being defined.

The section with heading My data allows selection a geometrical feature on the primary item which will be used in this constraint. The Reference Plane CLFA has been selected which represents the centre-line of the pump.

The section with heading Partner data allows selection a geometrical feature on the partner item which will be used in this constraint. Again, this equipment has a pre-defined CLFA Reference Plane representing the centre-line of the pump.

• If pre-defined reference planes do not exist on an element, then the Pick reference plane option can be pressed, and you will be asked to pick a reference P-point or P-line.
