Round-Anything is primarily a set of OpenSCAD utilities that help with rounding parts, but it also embodies a robust approach to developing OpenSCAD parts. I built this library to solve some of my own struggles with rounding and OpenSCAD as radii, internal radii, in particular, can be a real pain to add in OpenSCAD. And the more you move away from shapes with 90 degree angles, the more difficult it becomes, effectively putting a complexity ceiling on parts you can produce in OpenScad. Because of how important radii in both making an appealing and strong part, reducing stress concentration etc. A library that focuses on radii as a core principle makes for a solid foundation for your parts. Furthermore, the heart of the library revolves around the polygon, this is because we're leveraging the battle-tested paradigm of extruding from 2d sketches of most CAD packages. I can't imagine making an OpenScad part without Round-Anything.

Incredible work! Thanks a lot for that. 🙇‍♂️
Maybe OpenSCAD doesn't have everything that we want embedded, but programming languages are SO extensible (even the ones not powerful as a full-featured language). Work like yours made things so much easier!

I saw this in recommendations and immediately expected the advice was "oh, just bludgeon everything with minkowski()". It was nice to be wrong.

Thanks Kurt, you've sold me with your library. Coming from using Sketchup ... and looking for alternatives because it is kind of abandoned, falls short on curves and export of STLs but also loving the paradigm of sketch and extrude, I'm gonna give it a go. Still gonna use sketchup for architecture though. Now, if I can see how you make components in OpenScad, think I'm ready (think I know the answer, it is a function but wanna see it)!

Best lib for openscad, amazing.

[@cr6925]

Excellent stuff. I started with openscad, loved it's "C" feel but soon bumped into its limitations. Using Design Spark mechanical solely now but still have a very a very fond space in my heart for openscad. 😊

[@meanman1992]

There are definitely limits.
Have you tried CadQuery, JSCAD or some of the alternatives?

[@flamy111]

I found your library looking for something to round corners on cubes in my existing design, but your video gave me a new insight on how to approach design in openscad. Thus far, I've been stitching together primitive shapes, using hull() function and sometimes using linear_extrude with polygons.
From now on when starting new designs I will try to think in terms of in terms of polygons as primitives when I'm going to use your library.

[@flamy111]

It looks like subscription form is not working.

[@meanman1992]

Awesome Alex. I think that's the way it should be done. Sketch and extrude is the workhorse in more traditional CAD packages for a reason :)

[@katherinefernald4312]

Is there a manual somewhere? Like a list of commands within Round-Anything and actually how to use them? I haven't been able to figure out the syntax just by watching snazzy videos and seeing rounded shapes. Thanks!

Hi,
I have the scad file running but I'm not seeing how to control the part thicknesses. in radiusExtrudeExample(); It looks like it defaults to 3 cm thick....in roundAnythingExamples.scad

[@michaelthompson8251]

topological optimization library?

[@dansw0rkshop]

Does it work for beveling text? I'm looking for something to add casting draft angle to text.

[@meanman1992]

No, it wont. You likely could use the "extrudeWithRadius" utility to add radius to text, or you could look at the code for that and change it to make your own "extrudeWithBevel" utility.

[@meanman1992]

I think you're more likely to have success with CascadeStudio or CadQuery, come to think of it.

Drawing with VSC? I find openscad very enjoyable coming from autocad/inventor/fusion... I still have so much to learn though.

[@meanman1992]

Nice, keep going, gets easier with practice.
and yup, I use VS-code for everything coding related, I'm pretty comfortable with the editor at this point.

[@klausstock8020]

I'd love to see a comparison against the Minkowski sum, to show the difference in speed. With some very simple parts, of course. While the minkowski() function is pretty simple to use (and not as flexible), you shift from complaining about the slowness of 3D prints to complaining about the slowness of OpenSCAD.

[@meanman1992]

I'm currently working on a community website for "Code-CAD" (like OpenSCAD). A good way to think of it is codepen crossed with a thing repository. You can check it out at cadhub.xyz/

@@herseem This should be fixed now. Can you try clicking the link in the verification email again and let me know if you have any trouble?

@@meanman1992 yes, it works now
