Thought I would step out of Vectric Aspire to find another manner in creating STL files. Here is something I have started with using OpenSCAD and the BOSL library. Attached is the .scad file I used for this. I am trying to figure out how I can integrate or add a .25 radius rounding to both the top and bottom. Using the "fast_distance" method in skin() gave me exactly what I was looking for. to start with (see the pic). Then I attempted to utilize the rounded_prism() function in place of the skin() function but came up with errors all the time. Any ideas?

You don't include an example or the error. When I constructed one the error was that the side faces are not coplanar. The second sentence of the rounded_prism docs does state this requirement. You might be able to add a rounded cap on each end of your skin output using offset_sweep to make a rounding.

Yes. That was the error I was referring to. Your recommendation then is to figure out how to use that offset_sweep command to put a rounding on the top and bottom of the vnf object which was built with the "skin" command, yes?

Yeah, you would use offset_sweep twice for the top and bottom of the skin object. I did a quick test: up(2.5) offset_sweep(botBot,h=.5,top=os_circle(r=.5)); and you get the result below. To get it really nice looking you'll need a custom profile that better matches the slope of your shape, with a smaller rounding arc.

I found something on thingiverse some years ago wrt rounding top and bottom edges. Modified by  Kevin Gravier - https://www.thingiverse.com/mrkmg/about -  Originally from: https://github.com/OskarLinde/scad-utils/blob/master/morphology.scad. There was a minor error in the code, but it works good enough for 3d printing.

fyi, it's a 1.6 mb file so cannot post it here [image: Screenshot 2024-08-25 at 7.30.11 AM.png] On Sat, 24 Aug 2024 at 03:11, Joe Weinpert via Discuss < discuss@lists.openscad.org> wrote: > Thought I would step out of Vectric Aspire to find another manner in > creating STL files. > > Here is something I have started with using OpenSCAD and the BOSL library. > > Attached is the .scad file I used for this. > > I am trying to figure out how I can integrate or add a .25 radius rounding > to both the top and bottom. > > Using the "fast_distance" method in skin() gave me exactly what I was > looking for. to start with (see the pic). > > Then I attempted to utilize the rounded_prism() function in place of the > skin() function but came up with errors all the time. > > Any ideas? > > Joe Weinpert > joe.weinpert@gmail.com > skidrowacademy.com > > [image: maybeSkin.png] > > > _______________________________________________ > OpenSCAD mailing list > To unsubscribe send an email to discuss-leave@lists.openscad.org >
