While extracting intermediate section forces for frame element by using open staad application object is used. It demands the length of member. But the code givem for deriving length of member from open staad is having some error. Also the forces extracted at 13 section are fine for Fy, Fz, Mx, My and Mz. But for Fx it shows single value for all 13 section which will be not possible in case of column. So please clarify.
