Use to indicate the path to the user-defined part dimension planes table. This table defines the planes in which dimensions are created. For example, you might want Tekla Structures to dimension round bars to the middle of the profile rather than the reference lineline between two reference points
For example, if the user picks two points to position a beam, these points form the reference line, and handles appear at the line ends.
Reference lines can be used in snapping in a snap switch.
You can also use a file name as a value. If the value is a file name, Tekla Structures searches for the file in the model, project, firm and profile folders (in this order).
