XS_CALCULATE_POLYBEAM_LENGTH_ALONG_REFERENCE_LINE
Category in Advanced options dialog box
Dimensioning: Unfolding
Use this advanced option to calculate polybeam length along the reference line instead of the centerline. By default, Tekla Structures measures polybeam length along the centerline of the beam, regardless of the Position in plane values of the beam.
Set this advanced option to
TRUE
to calculate polybeam length along the reference line. Set it to
FALSE
(default) to calculate along the centerline.
When this advanced option is set, Tekla Structures ignores all unfolding parameters defined in the unfold_corner_ratios.inp file. However, this only affects polybeams with straight sections. The length of polybeams with curved chamfers is always controlled using unfold_corner_ratios.inp.
This advanced option is model specific and the setting is saved in the options database.
The centerline option is always a safe alternative, because other modifications do not impact on it. For example, if you calculate length using the reference line and you have used offsets to move the beam, the result may not be the true length of the beam.
When
XS_USE_OLD_POLYBEAM_LENGTH_CALCULATION is set to
TRUE
, this advanced option is not used, even though results might be the same in most cases. To obtain reliable results, especially for Net Length, we recommend that you do not set
XS_USE_OLD_POLYBEAM_LENGTH_CALCULATION
to
TRUE
.
