Understanding bounding boxes and TSO files

To populate the bounding boxes and TSO files, Teamcenter loads the JT file and then extracts the bounding box information. It adds that information to the Teamcenter bounding box table (PBOUNDINGBOX) and then creates the TSO file as a named reference in the JT dataset.

You can inspect the bounding box data for a selected part by adding bl_itemrev_bounding_box to the displayed properties in Structure Manager. This property shows the following values of the bounding box in the local coordinate space of the node:

• x minimum
• y minimum
• z minimum
• x maximum
• y maximum
• z maximum

Optionally, you can refine the accuracy of the proximity search when using TSO files. To configure the cell size of the TSO file, change the setting of the TC_JT_voxel_size preference from its default value of 12.75 millimeters. Some testing with sample geometry may be necessary to find the optimum cell size.
