The following ten types of standard bounding boxes are available for a support.

  • Supported (BBR) - This bounding box is aligned along the cross-section of the primary supported port. In other words, the x-axis is identical to the route feature direction. This definition is most widely used in the By Point command support joint definition.

  • TangentialToSupported (TANGENT_BBR) - This bounding box calculates the tangent bounding box when the number of pipes is more than one. This bounding box is aligned along the tangent to the set of pipe cross sections.

  • AlternateTangentialToSupported (TANGENT_ALT_BBR) - This bounding box calculates the tangent bounding box when the number of pipes is more than one. The tangent used is of the opposite side from the Tangent_BBR bounding box.

  • SupportedVertical (BBRV) - This bounding box is aligned along one axis of the primary reference port and also along the global Z-axis.

  • Supporting (BBS) - This bounding box is aligned along the plane of the supporting port.

  • SupportingVertical (BBSV) - This bounding box is aligned along the plane, which is vertical and aligned along the structure direction.

  • SupportedAndSupporting (BBSR) - This bounding box is aligned along the plane perpendicular to the XY plane of the supporting reference port. This definition can be used in the By Struct command to ensure that the support is perpendicular to the structure’s supporting plane.

  • GlobalSupportedX (GBBR_X) - This bounding box is created such that its normal is aligned with the global X direction. That is, the bounding box is in the global YZ plane.

  • GlobalSupportedY(GBBR_Y) - This bounding box is created such that its normal is aligned with the global Y direction. That is, the bounding box is in the global XZ plane.

  • GlobalSupportedZ (GBBR_Z) - This bounding box is created such that orientation of the box is always aligned with the global Z-axis.

The following example illustrates the side and top views of the different standard bounding box planes:

Bounding Box Planes_2015

In the previous example, all reference planes show only orientation of the bounding box. The different planes have the same root point, which is the origin of the route reference port. This point is the origin of the route port. The point is the intersection point, which is generated by projecting the structural axis toward the pipe and intersecting with the pipe axis.

Use Cases

Bounding boxes are useful when creating frame type assemblies. They provide you with reference ports that you would otherwise need to create using connection objects or joint offsets.

Because you sometimes need more freedom than a rigid joint allows, joint offsets do not always work.

The following examples illustrate different bounding box use cases:




Combination of Vertical and Horizontal Pipes

Bounding boxes for combinations of vertical and horizontal pipes depends on the first pipe selected. If a horizontal pipe is selected first, then bounding box is created only around horizontal pipes. In this case, all the vertical pipes are ignored, as shown in the following example. If, however, a vertical pipe is selected first, then only vertical pipes are considered for bounding box creation.
