XS_MAX_ANGLE_TOLERANCE_BETWEEN_COMPLEX_MAIN_PARTS
Category in Advanced options dialog: Dimensioning - parts
Use this advanced option to define
the maximum angle range (0...1) within which Tekla Structures dimensions
non-parallel parts as one. The default value is 0.01.
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.
