Accessing the Bounding Box
Plant Simulation provides these read-only attributes to measure the bounding box of the visible graphics of an object:
_3D.BoundingBoxCenter, _3D.BoundingBoxMax, _3D.BoundingBoxMin, and _3D.BoundingBoxSize.
Note:
All data concerning the bounding box relate to the local object coordinate system.
The individual values of the bounding box relate to each other as follows:
_3D.BoundingBoxMin plus _3D.BoundingBoxMax divided by 2 results in the _3D.BoundingBoxCenter.
_3D.BoundingBoxMax minus _3D.BoundingBoxMin results in the _3D.BoundingBoxSize.
_3D.BoundingBoxMax has to be equal to or greater than _3D.BoundingBoxMin.
