Selectthe equipment to constrain.
-
Select Constraints on the Place Equipment Controls.
-
Select Parallel from the Add Constraint list.
-
Select a surface on the equipment. For example, if you have a pump you want to make parallel to another pump, you would pick a pump surface. Use QuickPick if needed.
-
Select a surface in the model to which to make the equipment surface you selected parallel. Again, use QuickPick if needed.
The equipment moves to make the surfaces parallel.

Understanding the Parallel Constraint
Parallel relationships can be set between the following objects:
-
Edge to planar surface
-
Surface to surface
-
Edge to edge
-
Edge to axis (implied axis of cylindrical objects)
-
Axis (implied axis of cylindrical objects) to axis (implied axis of cylindrical objects)
In terms of behavior, the parallel relationship is similar to align. However, while the align relationship rotates and moves an equipment object, the parallel relationship only rotates the object. As such, if you orient a pump by setting a particular nozzle axis parallel to a nozzle axis on a different equipment object, only the orientation of the equipment is affected, not its location. This option is not available for Designed Equipment.
