Question: From Tekla Structures version 15.0 onward the setting XS_CHAMFER_ACCURACY_FACTOR does not affect polybeams. Is there another advanced option to manage the segments for polybeam chamfers?
 
Answer:

The XS_CHAMFER_ACCURACY_FACTOR advanced option has been changed to only affect contour plates.
  • You can control the number of segments of polybeam chamfers using several options, but the most useful one is XS_POLYBEAM_CHORD_TOLERANCE. It controls how many segments are used to make the curve, much in the same way as XS_CHAMFER_ACCURACY_FACTOR.
  • The curves affected by XS_POLYBEAM_CHORD_TOLERANCE are those with an inner radius larger than given by XS_POLYBEAM_ADAPTIVE_SLICE_RADIUS_LIMIT.
  • These should be enough to initially control the number of segments. However, there is another option that controls the maximum angle between the chords in the polybeam: XS_POLYBEAM_MAX_ANGLE_BETWEEN_CS (default = 30 degrees).
All of these options need to be put in your initialization file (e.g. user.ini).
