## Making an elbow

 This post has NOT been accepted by the mailing list yet. Hello, I am new to this forum.   I have looked for a long while for a good 3D design package, and OpenSCAD simply blows all of the rest of them away.  I have made several successful designs for 3D printing, and the technique is far ahead of trying to design with a graphic interface. Right now, I am making a small "elbow" (a right angle pipe bend), and the attached SCAD file is what I have used.   Although this will work fine in the application, esthetically, I'd rather have a smooth bend at the junction, as is usual in pipe elbows.   I'd be very grateful if someone would explain how I could change my design to achieve such an effect.

 A "cheap" way would be to use spheres, as shown in the following code. //right angle tube for Richard Pitz's art system \$fn=60; difference() {   union()  {     cylinder(40, 9, 9, center = false);     translate([0, 0, 40]) rotate([0, 90, 0]) cylinder(50, 9, 9, center = false);     translate([0, 0, 40]) sphere(9);   }     union()  {     translate([0, 0, -0.5]) cylinder(39, 6, 6, center = false);     translate([1.5, 0, 40]) rotate([0, 90, 0]) cylinder(49, 6, 6, center = false);         translate([0, 0, 40]) sphere(6);   } }//difference If you want even softer bows you can try to use code like difference() {   rotate_extrude(angle=90)  translate([15, 0, 0])circle(9);   rotate_extrude(angle=90)  translate([15, 0, 0])circle(6); } of couse there are also good libraries out there in Thingiverse (e.g. http://www.thingiverse.com/thing:1839527) or you can try with
