ViewSCAD is a module that renders within a Jupyter notebook 3D objects described in the OpenSCAD language, or described using the SolidPython module. It provides a workflow for CAD design completely within the Jupyter notebook.
ViewSCAD utilizes the
openscad executable to render objects, and as such, OpenSCAD must be installed on your system.
ViewSCAD installs simply with pip:
pip install viewscad
ViewSCAD uses the
pythreejs notebook extension to render the 3D graphics.
If you intend to use
jupyter notebook, you should be all set. However, if you intend to use
jupyter lab, additional steps are necessary to get
pythreejs working in the lab. Firstly, you must install node.js and npm. Then you must install the lab extensions:
jupyter labextension install @jupyter-widgets/jupyterlab-manager
The following shows how to use ViewSCAD to render a SolidPython object in Jupyter:
ViewSCAD attempts to locate your openscad executable, based on your platform, but failing that, you can set the
OPENSCAD_EXEC environment variable to point at your
openscad command-line executable, or pass it in the constructor of the renderer:
renderer = viewscad.Renderer(openscad_exec='path_of_my_openscad')
You can also render OpenSCAD code:
The renderer can also create an
.STL file directly by simply adding an
By double-clicking on a rendered object, you can select faces, edges, and vertices, and learn their indices. This allows you
to use several useful utilities, like
Renderer.rotate_face_down() orient the object with a particular face downward,
Renderer.place_on(), which lets you place one object upon another:
