Hi yakas, the compass measurements will need to be converted to regular angle measurements, it looks like Brian has included information above on how to do that, please let me know if you are still stuck on that part.

Once you have converted those, you can then use polar coordinate notation to enter in the coordinates:
http://moi3d.com/2.0/docs/moi_command_reference1.htm#__XYZ%20/%20Distance%20/%20Angle

Polar coordinates are entered using the < symbol in the form of:   dist<angle

So for example to make a line that has a length of 5 and an angle of 32 degrees, you first place the start point of the line and then for the second point enter in polar coordinates by typing this:    5<32   and push enter. That will tell MoI to place the current point at a distance of 5 units and an angle of 32 degrees away from the previous entered point.
