Hi, cool thanks for that, but, if i use the straight truss or insert truss tool, it places a truss object that i can connect the motors to and it becomes a system. in the object properties there is button for select system and change system trim. the system behaves as i would expect, however i cannot attach a light.
if i convert the truss to a hanging position, i can attach a light, however the motors no longer track the truss and the buttons for the select system are gone.
