Richard,
I think I found a way better than yours. If I rotate global coordinates means my axis (X,Y,Z) will be different at my model. And this isn't interessing once have another things linked around these axis. So, if just change the default view in Configure Setup > Graphics Settings, solve our problem. If we can't change Project North in Stress Iso, its better change the visualization, cause CAESAR reads the default view for the axis of project north.
I hope had helped.
