You can exaggerate narrow dimensions to make them easier to read.
When you enable the exaggeration of the dimensions, a dimension that is narrower than the defined limit is enlarged. If there are many exaggerated dimensions, Tekla Structures arranges them automatically. Setting exaggeration consists of selecting the exaggeration limit and the exaggeration scale, enabling the exaggeration and setting the direction, origin, width, position and height for the exaggerated dimensions.
For single-part , assembly and cast unit drawings, save the dimension exaggeration properties on object level in an open drawing into a dimension properties file, which you can take into use when you modify dimensioning rules.
Limitation: Exaggeration works only if the dimension extension lines are long. Set Short extension line to No on the General tab of the Dimension Properties dialog box.
