3D Printers Are Awesome!!!
But they don’t work in a vacuum: they need models
Christopher Olah ([email protected]) Programmatic CAD
Thingiverse is awesome!
But the models still need to come from somewhere.

Commercial CAD
There are very powerful commercial offerings in CAD, but theypresent issues...
They cost oodles of money.
They aren’t open source.

Enter: openscad
Around 2008, there wasn’t much in the way of open source CAD,but in 2009...

Programmatic CAD
Programmatic CAD has a number of advantages:
Firstly, repetitive tasks can be automaticaly done
Objects can be designed parametrically, so that a whole bunchof objects can be designed in a single fell swoop
All the usual tools for open source development can be used

Openscad, awesome as it is, is not perfect.
The underlying engine, openCSG, is prone to errors on someof the more complicated types of objects
One can’t get nice beveled connections between parts ofobjects
Openscad’s programming language aspects are not as strongas they may at first appear

Rise the Python-Openscads!
In the first half of 2011, a bunch of python-openscad hybridssprang into existence, fixing the programming troubles of openscad.

Around the same time, I released surfcad...

The Future
openscad is slowly being polished by Marius Kintel
I’m working on a new CAD tool, implicitCAD, which aims toresolve all the issues outlined with openscad.
GUI/programmatic CAD hybrids?

ImplicitCAD
Smoothed unions, intersections, differences. Also shells.
Full programmatic capabilities via haskell
Extensibility in a new direction (smoothed unions etc couldtrivially be created in language)
more accessible CSG
