TSAC-2605 Reinforcement

In Rebar shape manager, a new tolerance value, Curve tolerance, has been added to the Tolerances tab. This value is used for recognizing the arc in a rebar that has multiple sequential bendings.

If the deviation of the rebar leg from the arc is less than the tolerance, multiple bendings are combined to one (or two) bendings with the arc radius as the bending radius.

TSAC-2576 Reinforcement

Rebar shape managertool that is used for customizing the bending shapes of reinforcing bars

Rebar shape manager can be used for bending shapes only and not for any other reinforcing bar properties.

has been changed so that multiple sequential bendings which form an arc are combined into one or more bendings (90 degrees or less) with the arc radius. This makes it possible to define bending shapes containing a large radius bending no matter how many individual bendings appear in the original bar geometry.

This functionality is in use when you set the new XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR advanced option to TRUE. The advanced option can also be set in a suitable .ini file:
SET XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR=TRUE

When the advanced option is set to FALSE (which is the default value), the bendings appear as multiple bendings and the shape is recognized as before.

TTSD-25123 Modeling

Previously, cross sections could sometimes get incorrectly renamed with a redundant extension " 2", when automatically renamed after importing profiles (for example, "A100 2 2", or "A100 2 2 2 2"). Now the deduplication numbers in cross sectiongeometrical form of a part sectioned perpendicular to its axis

names are incremented correctly (for example, "A100 3", "A100 4", and so on).

TTSD-24549 Modeling
