Please do not use this repository for new projects. Use the CadQuery 2.x repo mentioned above.
CadQuery has several goals:
Using CadQuery, you can write short, simple scripts that produce high quality CAD models. It is easy to make many different objects using a single script that can be customized.
You can find the full cadquery documentation at
We also have a Google Group to make it easy to get help from other CadQuery users. We want you to feel welcome and encourage you to join the group and introduce yourself. We would also love to hear what you are doing with CadQuery. https://groups.google.com/forum/#!forum/cadquery
Installation instructions for all following use cases can be found
It is currently possible to use CadQuery for your own projects in 4 different ways:
If you are interested in trying CadQuery without installing anything, your best option is to experiment with CadQuery scripts running on a Jupyter server.

That button will launch a Jupyter Server pre-configured with CadQuery and its dependencies. It contains a folder with many useful examples to showcase CadQuery's features.
The easiest way to get started with CadQuery is to Install FreeCAD (version 16+) (
http://www.freecadweb.org/ <http://www.freecadweb.org/>), and then to use our great CadQuery-FreeCAD plugin here:
It includes the latest version of cadquery already bundled, and has super-easy installation on Mac, Windows, and Unix.
It has tons of awesome features like integration with FreeCAD so you can see your objects, code-autocompletion, an examples bundle, and script saving/loading. Its definitely the best way to kick the tires!
Awesome! CadQuery is built with this attitude in mind. If none of the existing usage methods work for you, you are more than welcome to forge your own path. You'll probably find the most success using the Docker image. You can alternatively install CadQuery as a standalone package.
The CadQuery docker image (
https://hub.docker.com/r/dcowden/cadquery/ <https://hub.docker.com/r/dcowden/cadquery/>_) includes cadquery and all of its dependencies. It can be used to run cadquery scripts without any installation required ( other than docker, of course)

This resin mold was modeled using cadquery and then created on a CNC machine:

The cadquery script is surprisingly short, and allows easily customizing any of the variables:
.. code-block:: python
import cadquery as cq from Helpers import show BS = cq.selectors.BoxSelector # PARAMETERS mount_holes = True # mold size mw = 40 mh = 13 ml = 120 # wire and fix size wd = 6 # wire diameter rt = 7 # resin thickness rl = 50 # resin length rwpl = 10 # resin to wire pass length # pocket fillet pf = 18 # mount holes mhd = 7 # hole diameter mht = 3 # hole distance from edge # filling hole fhd = 6 # DRAWING # draw base base = cq.Workplane("XY").box(ml, mw, mh, (True, True, False)) # draw wire pocket = cq.Workplane("XY", (0, 0, mh)).moveTo(-ml/2., 0).line(0, wd/2.)\ .line((ml-rl)/2.-rwpl, 0).line(rwpl, rt).line(rl, 0)\ .line(rwpl, -rt).line((ml-rl)/2.-rwpl, 0)\ .line(0, -(wd/2.)).close().revolve(axisEnd=(1, 0))\ .edges(BS((-rl/2.-rwpl-.1, -100, -100), (rl/2.+rwpl+.1, 100, 100)))\ .fillet(pf) r = base.cut(pocket) # mount holes if mount_holes: px = ml/2.-mht-mhd/2. py = mw/2.-mht-mhd/2 r = r.faces("<Z").workplane().pushPoints([ (px, py), (-px, py), (-px, -py), (px, -py) ]).hole(mhd) # fill holes r = r.faces("<Y").workplane().center(0, mh/2.).pushPoints([ (-rl/2., 0), (0, 0), (rl/2., 0) ]).hole(fhd, mw/2.) show(r)

KiCad uses cadquery to build high quality models of electronic components. (

We would love to link to your cadquery based project. Just let us know and we'll add it here.
If you are familiar with jQuery, you will probably recognize several jQuery features that CadQuery uses:
CadQuery is based on OpenCasCade. CadQuery shares many features with OpenSCAD, another open source, script based, parametric model generator.
The primary advantage of OpenSCAD is the large number of already existing model libraries that exist already. So why not simply use OpenSCAD?
CadQuery scripts have several key advantages over OpenSCAD:
#. The scripts use a standard programming language, Python, and thus can benefit from the associated infrastructure. This includes many standard libraries and IDEs #. More powerful CAD kernel OpenCascade is much more powerful than CGAL. Features supported natively by OCC include NURBS, splines, surface sewing, STL repair, STEP import/export, and other complex operations, in addition to the standard CSG operations supported by CGAL #. Ability to import/export STEP We think the ability to begin with a STEP model, created in a CAD package, and then add parametric features is key. This is possible in OpenSCAD using STL, but STL is a lossy format #. Less Code and easier scripting CadQuery scripts require less code to create most objects, because it is possible to locate features based on the position of other features, workplanes, vertices, etc. #. Better Performance CadQuery scripts can build STL, STEP, and AMF faster than OpenSCAD.

Cadquery 2.0 is under way. 2.0 is based on pythonOCC directly ( rather than FreeCAD ), and is under heavy development.
Beginning with version 2.0, CadQuery has moved to a new home at
Work is underway on a stand-alone gui here:
Work by Fragmuffin is ongoing with the
cqparts <https://github.com/fragmuffin/cqparts>_ repo.
Adam Urbańczyk has been working hard on his own
CQ fork <https://github.com/adam-urbanczyk/cadquery>_ which uses only PythonOCC instead of FreeCAD.
Work has begun on Cadquery 2.0, which will feature:
#. Feature trees, for more powerful selection #. Direct use of OpenCascade Community Edition (OCE), so that it is no longer required to install FreeCAD
