I am working on a project to 3D print a headlight bezel for an old Corvette. I have the main part designed in OpenSCAD (see attached picture), but I need to figure out how to measure/design/integrate the part shown in the yellow circle on the picture. Any suggestions? <http://forum.openscad.org/file/t1309/bezel.jpg> -- Sent from: http://forum.openscad.org/

Something beginning like this? $fn=30; difference(){ rotate([0,90,0]){     rotate_extrude(convexity=10) scale([1.5,1,2]) translate([1,0,0])  circle(r=1); } translate([-5,-5,-3]) cube([10,10,5]); } translate([-3,2,2])     rotate_extrude(convexity=10) scale([1.5,1,2]) translate([1,0,0])  circle(r=1); translate([3,2,2])     rotate_extrude(convexity=10) scale([1.5,1,2]) translate([1,0,0])  circle(r=1); On 01/16/2018 11:58 AM, cbernhardt wrote: > I am working on a project to 3D print a headlight bezel for an old Corvette. > I have the main part designed in OpenSCAD (see attached picture), but I need > to figure out how to measure/design/integrate the part shown in the yellow > circle on the picture.

Out a line at that point and use a hull You can tilt the line Sent from my iPhone > On 17 Jan 2018, at 12:58 AM, cbernhardt <charlie@carols62.com> wrote: > > I am working on a project to 3D print a headlight bezel for an old Corvette. > I have the main part designed in OpenSCAD (see attached picture), but I need > to figure out how to measure/design/integrate the part shown in the yellow > circle on the picture.

What I really need is a function that allows the input of randomly spaced 3D points and produces a 3D mesh surface. Is there such a function?

OpenSCAD is not very good in rounding freely composed forms. For 2D shapes you can use offset(), but there is (currently) no counterpart for 3D objects, besides minkowsky() which is very slow. In your case you could give the surface() command a try. It expects a PNG (grayscale value = height between 0 and 100) or a matrix of Z-heights. Both representations can easily be meshed into a "mountain" if you can do without "overhanging rocks". -- Sent from: http://forum.openscad.org/

I created a 3D mesh surface in AutoCAD, used a program called AcuTrans3d to give it thickness, exported it as an STL file and imported it into OpenSCAD (green area in attached picture). <http://forum.openscad.org/file/t1309/fillet_green.jpg> -- Sent from: http://forum.openscad.org/
