Creating blended fillets

  • Offset all the surfaces by the fillet radius.
  • Intersect them and get a complete curve all around.
  • Delete the offsets
  • Use Pull to suck the intersection curve back to each of the original surfaces.
  • Trim the surfaces with the pulled curves.
  • Pipe the intersection curve to the fillet radius.
  • Trim the pipe with the pulled back curve.
  • Stir gently over low heat, serve immediately.
  • If the pipe winds up having a seam within the final fillet, it might be better to sweep1 a circle around the curve of intersection instead, making sure that the seam in the circle is outside where the final fillet will be trimmmed to. - Pascal
