XS_EQUAL_SHAPE_DIMENSIONS_TO_BOTH_ENDS_LIMIT
Category in Advanced options dialog box
Dimensioning: Parts
Shape dimensions are automatically shown on both ends of a beam, even if the dimensions are the same. You can change this by entering a value in millimeters for this advanced option.
This advanced option is role specific. When the type SYSTEM(ROLE) is in use, the default value is used. When the type MODEL(ROLE) or DRAWING(ROLE) is in use, you can change the value, which is then the same for all users in the current model.
Example
If you set this advanced option to 300, and a part is 300 mm shorter in one direction, Tekla Structures only displays the dimension in the longer direction. Use millimeters in all environments.
