Looking at the documentation, it looks like all I need to do is to download the libraries into "$HOME/.local/share/OpenSCAD/libraries", but either that is not working properly or BOSL2 examples are broken (I suspect I'm doing it wrong). I am also not sure if that is considered best practice. For example, when I try to render BOSL2logo.scad I get the following warnings and errors: ... Used file cache size: 1 files Compiling design (CSG Tree generation)... WARNING: variable pitch_angle not specified as parameter in file BOSL2logo.scad, line 24 <24,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/examples/BOSL2logo.scad> WARNING: variable spiral_angle not specified as parameter in file BOSL2logo.scad, line 24 <24,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/examples/BOSL2logo.scad> ERROR: Assertion '((all_integer([teeth, mate_teeth]) && (teeth >= 3)) && (mate_teeth >= 3))' failed: "Must give teeth and mate_teeth, integers greater than or equal to 3" in file ../gears.scad, line 2433 <2433,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/gears.scad> TRACE: called by 'bevel_gear' in file ../gears.scad, line 2600 <2600,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/gears.scad> TRACE: called by 'bevel_gear' in file BOSL2logo.scad, line 24 <24,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/examples/BOSL2logo.scad> TRACE: called by 'children' in file ../color.scad, line 47 <47,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/color.scad> TRACE: called by 'recolor' in file BOSL2logo.scad, line 23 <23,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/examples/BOSL2logo.scad> TRACE: called by 'children' in file ../distributors.scad, line 1883 <1883,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/distributors.scad> TRACE: called by 'translate' in file ../distributors.scad, line 1883 <1883,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/distributors.scad> TRACE: called by 'for' in file ../distributors.scad, line 1880 <1880,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/distributors.scad> TRACE: called by 'xdistribute' in file BOSL2logo.scad, line 10 <10,/home/ebo/.local/share/OpenSCAD/libraries/BOSL2/examples/BOSL2logo.scad> ... and with a number of others I also get the error: ERROR: The given mesh is not closed!

My guess is that the example got stale, that it didn't keep up with the evolution of the library. I think that some of the examples (e.g. boolean_geometry.scad) are not intended to be 3D objects.  I see a couple of errors on some of the others in that directory (e.g. spherical_patch.scad previews OK but doesn't want to render). Revar?  Adrian?

Well, that's embarrassing. Yes, the examples got stale. I've checked in fixes for both errors I saw in the examples folder. - Revar > On Mar 3, 2024, at 6:36 PM, Jordan Brown via Discuss <discuss@lists.openscad.org> wrote: > > On 3/3/2024 6:04 PM, John David via Discuss wrote: >> Looking at the documentation, it looks like all I need to do is to download the libraries into "$HOME/.local/share/OpenSCAD/libraries", but either that is not working properly or BOSL2 examples are broken (I suspect I'm doing it wrong).

Revar, no biggie. It happens to the best of us. Let me know if you need help breaking anything else ;-) On Sun, Mar 3, 2024 at 10:21 PM Revar Desmera <revarbat@gmail.com> wrote: > Well, that's embarrassing. Yes, the examples got stale.
