Rocksim v9.0- Creating a Rounded Fin?

[jmmome]

I apparently created a rounded fin in Rocksim for a rocket I'm making, but I accidentally deleted the Rocksim file. I've recreated the rocket in Rocksim, but I can't figure out how to re-make the rounded fin in Rocksim. Would appreciate some guidance.

I do OR rather than RS, but isn't this simply an elliptical finset w/ 7" root, 8" span, 1.5" tab, & .25" thickness?

It is what you describe. However, Rocksim doesn't allow for an elliptical fin choice. But Rocksim does have a "chamfer radius" button. I re-read the definition of that option, and it is the method to round the sharp edges of a fin design. I still don't remember using it before, but apparently I must have.

Thank you- your response made me go back to Rocksim and check the definitions of all the buttons within the fin design mode.

what version of Rocksim are you using? RS9 has an "elliptical" option under "Fin Set"

I tried to upload a screen shot, but TRF isn't allowing an upload right now...

edit: attachments seem to work now...
