RebarShapeTerminationsData.HookAngleAtStart Property

Identifies the hook angle (in degrees) at the start of the rebar shape. The angle must be at least 0 and no more than 180. In case it is 0 it will be considered that the shape doesn't have a hook. Common values are 0, 90, 135, and 180. Setting this property to a value strictly greater than 0 and less or almost equal with 180 will set the HasCrankAtStart to false and EndTreatmentTypeIdAtStart to ElementId.InvalidElementId.
