Unexpected rotation of surfaces by Feature Editing Surface Offset command

Legend

Hello, I attached a model where the inner surfaces are rotating by Feature Editing - Surface Offset command in Meshing Toolbox:

The original Solid looks like this:

 

Offset surface is rotating_Before.jpg

 

After using this command, and selecting Surfaces 8408 and 8409 (inner surfaces) with Dialog Select button, the inner surfaces are rotating with 90°:

 

Offset surface is rotating_After.jpg

 

In this case Femap unexpected modify geometry, like by Cleanup command (see my other post "Nonmergeable curves modified after Cleanup"). Can Siemens correct this problem in next versions?

 

Best regards,

If you use the "Auto Extend" option to let FEMAP pick both surfaces with the selection of just one, it works fine.  The rotation happens when both surfaces are picked, with both picked, they go through the offset code one at a time, I will look at updating the code to do the same thing in the future, but for now, use the "Auto Extend" option.
