hi @Mouhammad_mazzaz 

Could you be more precise ?

is this the IRobotFeResultPrincipal interface? 

The local axes of bars have the same color as the global ones.

Hi  Stephane ,

Thank for your reply, 

Please find the attached photo  https://www.screencast.com/t/RRvgtji8q , here we have 1,2 and 12 , what they meant by M1 is that mean the moment about the local axis 1 ?

As I know that the local axis in robot has the same name of the global axis x,y and z  please see the attached photo 
https://www.screencast.com/t/NZkRSpnZD 

so what is the difference between MX and M1 ?

what is the color code of the axis 1, 2  ? 

thanks in advance

Hi @Mouhammad_mazzaz 

You can see directions (trajectories) of principal moments M1 and M2 by presenting crosses.
