Define and modify units
Tekla Structural Designer allows you to switch between Metric and US customary units. Furthermore, by following the below instructions you can select the units which you want to use in the selected unit system. For example, if you use US customary units, you can change say, the Force unit to input in either kip or lb, or the Dimension unit to have dimensions measured in either feet, inches, fractional inches, feet and inches, or feet and fractional inches.
