Question RockSim 8: Drawing "Curvy" Fins

Hi, all! This is basically a follow-up to the threads about how difficult it is to draw "non-standard" fins in RockSim, and to the "Semroc SST Shuttle 1" thread where I mentioned I was trying to recreate a Centuri Quasar from the 1972 catalog. (See first two images below.)


I took the fin pattern from this link at JimZ:

http://www.dars.org/jimz/kc-7.htm

...and traced it on graph paper with 1/4" squares (Figure 3). I've managed to (accidentally) round the corners of some fins in RockSim, but I didn't really figure out how to do it predictably. So I'd like some help with "curving" the angle down by the aft end (back side) so it's smoother and more streamlined... like the original in the link above.


I've attached the RockSim file below. Sandman, can ya help me here?


Thanks in advance,

--Jay
