Dear all, I'm struggling trying to figure it out to accomplish the following box, that is in irregular shape, like the following picture <http://forum.openscad.org/file/t2322/box-1.jpeg> . Another view <http://forum.openscad.org/file/t2322/box-2.jpeg> Looks like the typical burger box, but with one side more tilted that the other mirrored one. How I can do it? I have tried with polygon, but it is quite complex task. Any insight would be grateful! Thanks //Giovanni -- Sent from: http://forum.openscad.org/

Giovanni-- A good approach for that kind of shape is to start in 2D. The top and the bottom are rounded rectangles, and the "middle" of your box is another one (although with different size, and maybe inclined?). So I started with that shape in 2D: module roundrec(size=[60, 40], radius=5, center=true) { offset(radius) offset(-radius) square(size, center); } To move it around I gave it a bit of volume: linear_extrude(height=0.001) roundrec(); Doing it three times with some movement: translate([0, 0, 15]) linear_extrude(height=0.001) roundrec(); translate([0, 1, 0]) rotate([5, 0, 0]) linear_extrude(height=0.001) roundrec([70, 53]); translate([0, 0, -15]) linear_extrude(height=0.001) roundrec(); With a hull() around that, you get this: [image: rounded_box.png] HTH El mié., 15 ago. 2018 a las 0:30, gmorchio (<gmorchio@gmail.com>) escribió: > Dear all, I'm struggling trying to figure it out to accomplish the > following > box, that is in irregular shape, like the following picture > <http://forum.openscad.org/file/t2322/box-1.jpeg> .

Antonio, great job! woah, and how can now convert it into a box, i have to replicate, do a differrence() or something to make it as a shell? -- Sent from: http://forum.openscad.org/

Indeed, that'd be a way to do it :-) [image: rounded_box_2.png] El mié., 15 ago. 2018 a las 20:21, gmorchio (<gmorchio@gmail.com>) escribió: > Antonio, great job! woah, and how can now convert it into a box, i have to > replicate, do a differrence() or something to make it as a shell? > > > > -- > Sent from: http://forum.openscad.org/ > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org > -- Saludos, Antonio

Thanks again Antonio. Last question, how did you create the cube to see thru the internal? Nice! -- Sent from: http://forum.openscad.org/

I just added a cube at the end of the box difference(). The see-through effect is equivalent to the debug modifier <https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#Debug_Modifier> (#). I *really* don't like the default pink of that modifier, so I did my own version with this module: module peek(alpha=0.2) { children(); color([0.5, 0.5, 0.5, alpha]) %children(); } El jue., 16 ago. 2018 a las 22:45, gmorchio (<gmorchio@gmail.com>) escribió: > Thanks again Antonio.
