I've been struggling for 2 hours now to create this rounded 15-sided n-gon inside Cinema 4D, without just importing the vector path and using Extrude or Loft, because it messes up the geometry.
So I used the plugin Archimedes to find out exactly what triangles I need to create so they can be 15 and rotated exactly at 24° (because 360/15=24) but now I'm struggling with the roundness of the object.
Here's my brief visual explanation: https://i.imgur.com/K6CXlku.jpg
Initial plan was using triangles and then Subdividing them but the Subdivision is working in a different way and it seems it can't do the job.
So I'm trying now with circles or semicircles but I can't do the math right.
