Why are the bars in Metal 3D assigned a moment coefficient equal to 1 when I have told the Portal Frame Generator to generate the data for the lateral buckling check?
 

The Portal Frame Generator does not know what the moment diagram of the frames generated in Metal 3D will be like; therefore a default value of 1 is provided. Users must change this value to that indicated in the selected code. Regarding the braced distance, the program does generate the data correctly.
