Defect number Development area Description
TSAC-2251 Concrete components

Floor layout now creates additional tabs for user-defined attributes in the Floor layout dialog box if there are a lot of user-defined attributes. Earlier, if there were a lot of user-defined attributes, the row spacing on the User defined tab was compressed to fit all the attributes on one tab.

When you set XS_AISC_WELD_MARK to FALSE, you can now control how the fillet weld size is interpreted using the new XS_ISO_LEG_LENGTH_AS_WELDSIZE advanced option.
Set XS_ISO_LEG_LENGTH_AS_WELDSIZE to:

  • TRUE to use the weld size as the leg length of the fillet welds
  • FALSE to use the weld size as the throat thickness of the fillet welds

Note that setting a weld prefix that affects the weld size overrides the value set in XS_ISO_LEG_LENGTH_AS_WELDSIZE.

TTSD-18600 Modeling

When saving the model with Save as, the model name is now restricted to 40 characters, like when creating a new model. The last 10 model paths are not shown in the Save as dialog box.
