TINK

Using TINK, you can choose as many branches as you require and they will be equi-spaced and central to the base circle.

Again like other Ty Harness Sheet Metal Applications you can choose more or less divisions to triangulate-out the pattern where the greater the number of divisions the less truncation error but at the expense of the processing time. If you want to print the pattern from TINK then set the maximum number of divisions (120) but say you need a lean VRML model then you can maybe get away with 48, and if you have to type in the 2D pattern coordinates into G code then maybe 12 or 24 points is all you need for the job.
