[[EM.Terrano]]'s Transmitter Set dialog and Receiver Set dialog both allow you to rotate an imported radiation pattern. In that case, you need to specify the '''Rotation''' angles in degrees about the X-, Y- and Z-axes. It is important to note that these rotations are performed sequentially and in the following order: first a rotation about the X-axis, then a rotation about the Y-axis, and finally a rotation about the Z-axis. In addition, all the rotations are performed with respect to the "rotated" local coordinate systems (LCS). In other words, the first rotation with respect to the local X-axis transforms the XYZ LCS to a new primed X^′Y^′Z^′ LCS. The second rotation is performed with respect to the new Y^′-axis and transforms the X^′Y^′Z^′ LCS to a new double-primed X^{′′}Y^{′′}Z^{′′} LCS. The third rotation is finally performed with respect to the new Z^{′′}-axis. The figures below shows single and double rotations.
