Is there a way to attach free form fins to transitions in the program? Working on my Hercules drawings and I can’t figure out how to land the sustainer fins to the airframe continuously because of the two transistions fore and aft. The root of the fin will not change with the change of the airframe.
thanks in advance.

If you attach the OpenRocket file for as far as you have gotten with a sketch of what you are trying to do, someone may be able to help you.
Sounds good, I’ll put it together after work today and post it.

No. You can, however, attach the fin to the body tube either ahead of or behind the transition, or you can put a very short body tube in the middle of the transition and attach it to that. If you put it on the smaller-diameter end of the transition it will render nicely but will have too much area for the drag and stability calculations; if you put it on a short body tube in the middle of the transition it won't render well (it'll show a gap), but will sim reasonably well.

Next release.... (trust me, I'm as tired of saying that as everybody is of hearing it).
