Long story made short. I drafted 120' of truss in my drawing (Using all 10' pieces). I then made it a hanging position. I then placed all my lights where I needed them. However, I found out that I have to loose the middle 4 pieces of truss due to a structural soffit in the room (don't mention a site survey). Is there a way to easily delete them? Or do I have to start from scratch? Can I also add truss and make it the same hanging position? Or is it once you make it a hanging position, is it done and you just have to start from scratch?
