here is what I do to find the firing points and engine glows for models:
* load the model in a 3D programm
* make a small ball with radius 1
* move the ball to where the firing points/engines should be
* check the coordinates of the ball and enter them to SpaceObjects file
* move to next firing point/engine glow

also there is a nice cheat (SHOWFIRINGPOINTS) that let's you check on the firing points and arcs on all the models in the game.
