Dimensioning: general

Set to TRUE to have Tekla Structures include the inch symbol in dimensions. The default value is TRUE. If you do not want to allow inch marks, set this advanced option to FALSE.

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.
