A sample assembly that shows a custom bounding box in the model is provided: HS Assembly V2\Diagnostic Supports\Reference Port and Bounding BoxDiagnostic Support. Two example bounding boxes are available, one for horizontal pipes and one for vertical pipes.
The sample support is meant to graphically represent the plane of the bounding box using a plate representation. Two cylinders are used to represent the Z-axis and the Y-axis of the high port. Two boxes are used to represent the Z-axis and Y-axis of the low port.
When Mirror = False
When Mirror = True
The sample support has two occurrence properties that you can use to control the behavior of the bounding box. The BBX Alignment property is used to specify how the Z-axis of the bounding box should be aligned within the plane.
-
Direct Towards Structure - The bounding box is parallel to the supporting structure.
-
Orthogonal to Global CS - The bounding box is parallel to the global coordinate system.
The BBX Mirror property is used to mirror the bounding box.
