Yes, I know what your talking about.. and you have a few simple modifications to work with.
1. The Design Spot 250 has two pan degree settings. The degree is the amount of spin from left to right that the light can move.
It should be set to 540 degrees on the light to match the 3D window.
2. Once this is done, then on the 3D window you may want to invert the pan and tilt to match the direction of the actual light. Here is a picture to help you find the pan and tilt inversion.
