 Applies To 
 Product:Ram Structural System; ISM
First Affected Version:15.00.00.00
 Found in Version:15.00.00.00
Fixed in Version:
Environment:All
 Area: Import/Export
Subarea:N/A
 Issue #:336010

Problem Description

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. 

Reason

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. 

Solution

Updated files can be downloaded to fix the problem until another release is made public. 

64 bit installations - RAM SS - ISM Fix for beam reactions x64

32 bit installations - RAM SS - ISM Fix for beam reactions x86

Do not use beam annotation with end reactions. unless the values are manually entered.
