Skew Angle: Define the skew angle for the diaphragm.
Is it an Intermediate or Pier/End Diaphragm?[Intermediate/Pier-End]: This parameter can be used to define whether the diaphragm is an intermediate diaphragm or a pier-end diaphragm.
Station [Start/ End]: If the diaphragm is defined as an intermediate diaphragm, a the station relative to the PGL can be specified by using this parameter to further define the diaphragm's location of the diaphragm. If the diaphragm is defined as a . This parameter is not applicable for pier-end diaphragm, this parameter will not be applicablediaphragms.
Select Pier/End: If the diaphragm is defined as a pier-end diaphragm, this parameter can be used to define the location of the diaphragm, as the support line can be selected. If the diaphragm is defined as intermediate, this parameter will not be applicable.
...
Material: Assign a material to the diaphragm. A material can either be imported or assigned from a previously defined one under Properties - Materials.
