The reaction from the "Left" end in Ram Steel is incorrectly being applied to the "End" reaction of the member in ISM (Structural Synchronizer) and the "Right" reaction incorrectly applied to the "Start" end in ISM. These should be reversed.
Furthermore, the magnitude of the end reaction exported is slightly larger than what is shown in Ram Steel due to the duplicate application of the beam self-weight reaction.
The problem does not affect Ram Steel or Ram Connection, only the exported reactions sent to ISM. When those reactions are used in detailing applications like AECOsim Building Designer or Revit for general assembly drawings, the automated annotation of beam reactions are reversed.
Fixed in version 15.02.00.00.
