Dimensioning: Unfolding

Use this advanced option 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 along the reference lineline between two reference points

For example, if the user picks two points to position a beam, these points form the reference line, and handles appear at the line ends.

Reference lines can be used in snapping in a snap switch.

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 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).

.

Note:

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.

Note:

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.
