  Re: unofficial new primitive -- "Rounded Corner"
 
[snipped Franklin's post] Some comments/questions: What is the definition of this part? Is it a section of a sphere? What are the angles and radii of the curved edges? Could you reverse the shape, so it is convex? This would make it easier to fit (...) (24 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives)
 
  Re: unofficial new primitive -- "Rounded Corner"
 
It is not part of a sphere. It can be thought of as a virtual cube which has had one corner sliced away in a curved fashion. Or to put it another way, it is the grey area in this image: "(URL) radii are "1", and its angles are 90 degrees (i.e., 1/4 (...) (24 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives)
 
  Re: unofficial new primitive -- "Rounded Corner"
 
(...) UPDATE! It _is_ part of a sphere, I just realized, a sphere having a radius of "the square root of 2"! This primitive is one octant of that sphere with three faces "planed/smoothed off" so that the resulting object will fit inside a cube (...)

  Re: unofficial new primitive -- "Rounded Corner"
 
Ooo, cool. That means each of the colored faces in your image is a 1-4disc.dat, right? That'll work very nicely. I'll forward this to the primitives committee. Do you mind if I use it in the skeleton leg file? Steve (...) (24 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives)

(...) Yup. (...) Go for it. :-) Also, if needed, please feel free to copy the image(s) for illustrating what this primitive is for. Franklin (24 years ago, 15-Sep-00, to lugnet.cad.dat.parts.primitives)

(...) To be more specific: could this file be re-oriented, so that figures like (URL) can be constructed as: 1 1 0 1 0 1 0 0 0 1 0 0 0 1 1-4disc.dat 1 2 1 0 0 0 1 0 1 0 0 0 0 1 1-4disc.dat 1 4 0 0 1 1 0 0 0 0 1 0 1 0 1-4disc.dat 1 14 0 0 0 1 0 0 0 1 (...)
