Use this module to generate a pie- or pizza- slice shape, which is particularly useful in combination with difference() and intersection() to render shapes that extend a certain number of degrees around or within a circle.

This OpenSCAD library is part of the dotscad project. Source code and full documentation can be found at https://github.com/dotscad/dotscad/

Thank you for this great library! It inspired me to try out my own approach (I have no idea if this approach has any advantages).

If you want to can see it here:

OpenSCAD pie slice

The pies do not slice well in Repetier when another difference is added (tube).

Interesting. I'm happy to take bug reports on github, though I don't use Repetier and can't for the life of me think why anything would have trouble with the way this shape is put together.

Never mind. My fault. The two objects in difference() were in the same position at the bottom. Enlarging the substracted object solved the problem!

Glad to know you figured it out. Coplanar edge issues can be a PITA.

Until Thingiverse gets their site in order so I can update the source file here, grab the file at https://github.com/ex-nerd/3d/blob/master/pie.scadhttps://github.com/ex-nerd/3d/... -- it has some updates that I think are nicer than the original.

Ignore this comment. For some reason Thingiverse forgot that I posted it and now I can't delete it.
