OpenSCAD MCAD Library OpenSCAD MCAD Library
===================== =====================
This library contains components commonly used in designing and moching up mechanical designs. It is currently unfinished and still undergoing considerable API changes however many things are already working. This library contains components commonly used in designing and moching up

changes, however many things are already working.

== Usage ==
You can import these files in your scripts with "use <MCAD/*.scad>", but some
files include useful constants which will be available with "include <MCAD/*.scad>",
which should be safe to use on all included files (ie. no top level code should
create geometry).

You are welcome to fork this project in github and request pulls. I will try to accomodate the community as much as possible in this. == Development ==
You are welcome to fork this project in github and request pulls. I will try to
accomodate the community as much as possible in this. If for some reason you
want collaborator access, just ask.
Github is fun (and easy), but I can include code submissions and other
improvements directly, and have already included code from various sources
(thingiverse is great :)
=== Code style ===
I'd prefer to have all included code nicely indented, at least at the block
level, and no extraneous whitespace. I'm used to indent with four spaces as
opposed to tabs or other mixes of whitespace, but at least try to choose a style
and stick to it.
=== Testing ===
I've started a minimal testing infrastucture for OpenSCAD code. It's written in
python and uses py.test (might be compatible with Nose also). Just type py.test
inside the lib dir in a terminal and you should see a part of the tests passing
and tracebacks for failing tests. It's very simplistic still, but it should test
that no syntax errors occur at least.
