module all(m) { m(); mirror([1, 0, 0]) m(); mirror([0, 1, 0]) { m(); mirror([1, 0, 0]) m(); } } I am finding strange this does not work. What would be the best solution for the above problem?

How do you mean not work? What does it do?

Works fine for me. all(); module all(m) { m(); mirror([1, 0, 0]) m(); mirror([0, 1, 0]) { m(); mirror([1, 0, 0]) m(); } } module m() { cube(10); } -- Sent from: http://forum.openscad.org/

I want to pass different modules like: module m() { cube(10); } module n() { ... } all(m); all(n); On 6/4/20, lar3ry <lar3ry@sasktel.net> wrote: > Works fine for me. > > all(); > module all(m) { > m(); > mirror([1, 0, 0]) > m(); > mirror([0, 1, 0]) { > m(); > mirror([1, 0, 0]) > m(); > } > } > > > module m() { > cube(10); > } > > > > > -- > Sent from: http://forum.openscad.org/ > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org >

Ahhh, modules aren't objects that can be passed. You would use children() : module all() { children(); mirror([1, 0, 0]) children(); mirror([0, 1, 0]) { children(); mirror([1, 0, 0]) children(); } } module m() { cube(10); } module n() { cube(20); } all() m(); all() n(); On Thu, 4 Jun 2020, 11:17 sean d'epagnier, <seandepagnier@gmail.com> wrote: > I want to pass different modules like: > module m() { > cube(10); > } > > module n() { > ... > } > > all(m); > all(n); > > On 6/4/20, lar3ry <lar3ry@sasktel.net> wrote: > > Works fine for me. > > > > all(); > > module all(m) { > > m(); > > mirror([1, 0, 0]) > > m(); > > mirror([0, 1, 0]) { > > m(); > > mirror([1, 0, 0]) > > m(); > > } > > } > > > > > > module m() { > > cube(10); > > } > > > > > > > > > > -- > > Sent from: http://forum.openscad.org/ > > > > _______________________________________________ > > OpenSCAD mailing list > > Discuss@lists.openscad.org > > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org > > > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org >

essentially there are userspace objects that can be passed as parameters, and rendered objects, like modules, and they live in different spaces On Thu, Jun 4, 2020 at 11:33 AM A.

Thanks for pointing out the use of children(), this makes a lot more possible. This is still a limitation compared to multiple parameters.. but I guess openscad doesn't allow mixing passed parameters with modules. On 6/4/20, A.

You can pass parameters to children via $ variables.

Not sure what your question was, but you can pass multiple modules as children. module twokids() { difference() { children(0); children(1); } } twokids() { cube(); sphere(); } On Thu, 4 Jun 2020 at 20:54, nop head <nop.head@gmail.com> wrote: > You can pass parameters to children via $ variables.

Yes, it is. But I do find it necessary sometimes. Even worse is use $p in the child module without it being a parameter!

I have learned a lot.. The $ variables hack is interesting, but I hope not to use it.
