## rounded surface help

 Hello, I tried to create a surface like the yellow part of this: http://bit.ly/K6mWIX with OpenSCAD without success. Have you got any advice on this? I guess it's very simple because it's a common shape but somehow I could't figure it out. Thanks a lot, gega

 use a section of a cone, start with cylinder(r1 = 20, r2 = 10, h = 10);On Mon, May 28, 2012 at 10:39 PM, Gergely Gati wrote: Hello, I tried to create a surface like the yellow part of this: http://bit.ly/K6mWIX with OpenSCAD without success.

 In reply to this post by Gergely Gati You could subtract a cone from a cube, and subtract the result from your part, or you could create a union involving a cone. Cone in openscad is done using cylinder(r1=10,r2=20); Regards Giles.

 Or just take the hull of two cylinders and whatever makes the other corners.On 28 May 2012 13:44, Giles Bathgate wrote: You could subtract a cone from a cube, and subtract the result from your part, or you could create a union involving a cone.
