This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.

The following template attributes give the bounding box of the objects as X, Y or Z minimum or maximum distances from the absolute zero (0,0,0):

• BOUNDING_BOX_MIN_X
• BOUNDING_BOX_MAX_X
• BOUNDING_BOX_MIN_Y
• BOUNDING_BOX_MAX_Y
• BOUNDING_BOX_MIN_Z
• BOUNDING_BOX_MAX_Z
• BOUNDING_BOX_X
• BOUNDING_BOX_Y
• BOUNDING_BOX_Z

These attributes are available for parts, assemblies, cast units, reference models, and reference objects.

Adding _BASEPOINT at the end of the attribute gives coordinates relative to the base point selected in the view, and adding _PROJECT at the end gives coordinates relative to the base point selected as the project base point. _BASEPOINT uses the current base point in the same way as the workplane uses the current workplane: If there is no current base point defined, _BASEPOINT provides values relative to model origin (Global).
