Coordinate System Help
 

I am new to Star-ccm+, and I am a little confused about the coordinate system. I am importing the frame of a multi-rotor copter, and I want to place a blade element model at each of the motor ends. However, I am not sure about the placement of each of these coordinates. Is there any way to find the coordinates of certain points on your model?
