Set this advanced option to TRUE to calculate polybeampart of a certain shape that is created as a continuous chain of beams passing through points that the user picks
The segments of the polybeam are straight, but segment intersections can be curved. For example, a beam that follows a zigzag line is a polybeam.
length using the legacy method where lengths of straight parts are added together, without taking the unfolding into account. If you set it to FALSE (default) and use the new method, the polybeam length is defined by unfolding the polybeam first and then calculating the length. This way of calculating gives a more accurate value for the polybeam length.
This advanced option is model specific and the setting is saved in the options databasedatabase file that contains the settings of model-specific general settings and advanced options
There are two options databases, the model options database (options_model.db) and the drawing options database (options_drawings.db).
Using this advanced option is not recommended, because the length may not be reported correctly in all cases, especially for polybeams with curved chamfers.
When you switch on this advanced option, other ways to calculate polybeam length are not used by Tekla Structures , for example, XS_CALCULATE_POLYBEAM_LENGTH_ALONG_REFERENCE_LINE , XS_DONT_USE_NEUTRAL_AXIS_FOR_RADIUS or the unfold parameter settings in file unfold_corner_ratios.inp.
