By default, Tekla Structures calculates the length of curved parts along the center axis. Use this advanced option to define the position of this axis as a ratio.

Tekla Structures calculates the location of the axis using the formula h=H/2.0*ratio. The default value is zero (0). Define the ratio as 1.0 to calculate length along the upper flange. Define the ratio as -1.0 to define the length along the lower flange.

This value is used in report and drawing templates.
