just discovered your new ccCompass plugin - sensational!!!
It took me a while though to understand the orientation values from the Plane tool. I was misleaded and confused because the reading in the DB Tree is different to the Primitive readings in the properties box. It seems that in the DB Tree the strike of the plane is shown, whereas in the Properties/Primitive the dipdirection is shown (which perfectly matches the fitted plane and fits dipdirection derived by normal estimations). Maybe it would be usefull to change the value shown in the DB Tree to avoid further confusion at some stage...
thanks a lot - very usefull tool
