Tekla Structures aligns slightly sloped dimension text. If the dimension text is sloped more than a certain degree, Tekla Structures flips the text.
Below is an example of a dimension text that is slightly sloped.
Below is an example of a flipped dimension text.
The default limit for aligning dimension text is 0.1 (5.74 degrees). When this limit is exceeded, the dimension text gets flipped. To adjust this limit, use the advanced option XS_TEXT_ORIENTATION_EPSILON.
