I haven’t used it extensively myself. I think you can just read the tutorials and maybe post specific questions if things aren’t clear. Be aware that sometime extension code is still available after the active funding is exhausted, so there may not be anyone to answer and you’ll have to see what you can figure out on your own.
Do you mean the beam borders (acceptance)? You can visualise your dynamic beam, if it has multiple control points by means of the sequence browser. The ARC type of beam with only two control points doesn’t work yet.
