## Fillet meeting a convex curve

 Hi, smarter people than me today… I needed to make a fillet between a straight edge and a gently curving away radius. Below is what it looks like if I use a square and subtract a circle.  I was in a hurry, and just nudged it and shaved it further until it was visually OK.  I have a library that would put fillets all over the part – but it would be overkill. Does anyone have a nifty library set up for these occasions?  Cheers, Alex Gibson admg consulting edumaker limited ·         Project management·         Operations & Process improvement ·         3D Printing _______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org

## Re: Fillet meeting a convex curve

 In reply to this post by alexgibson The method using a bunch of offsets is the easiest, if that can do the job. I wrote an "offset_stroke" that will take a series of points and draw a 2d curve with specified width and with filleting to an arbitrary angle at both ends.  (It's in BOSL2.) I'm very interested in this kind of problem, but I think the solutions often need to be integrated with the method you used to make the curved shape. That is, you need to have a representation of the curve and use that to develop the fillet.  I'm actually planning to write a function that will blend two point lists with a curve between them.  But of course, all of these types of approaches require that you have a point list rather than geometry.   -- Sent from: http://forum.openscad.org/_______________________________________________ OpenSCAD mailing list [hidden email] http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org
