The next steps require NPM and Node.js. The JSCAD project always develops with the latest LTS releases, so install these versions.

Install the CLI for General Use

The CLI can be installed for general use using NPM.

npm install -g @jscad/cli

Once installed, the CLI can be invoked using

jscad -v

Install the CLI as Part of a Project

If a general installation is not possible or desired, then installation as part of a project is possible.

cd myproject
npm install -D @jscad/cli

This will add the CLI package as a development dependency. The CLI can be invoked using

npx jscad -v
npx jscad

These two commands will show the version of the CLI, and a general help message.

Using the CLI

Simply invoke 'jscad' using various options. Here are some examples.


jscad mydesign.js # -- convert mydesign.js to mydesign.stl as default

jscad mydesign.js -o test.stl # -- convert mydesign.js to test.stl

jscad frog.stl -o test.js # -- convert frog.stl to test.js

jscad mydesign.js -of amf # -- convert mydesign.js into mydesign.amf

For multi-part models, you can pass the generateParts flag -gp to output each part as a separate, numbered file:

jscad mydesign.js -gp # -- convert mydesign.js into mydesign-part-1-of-2.stl and mydesign-part-2-of-2.stl

You may also pass the zip flag -z to zip generated files into one .zip file:

jscad mydesign.js -z # -- convert mydesign.js into mydesign.zip which contains: mydesign.stl

jscad mydesign.js -gp -z # -- convert mydesign.js into mydesign.zip which contains: mydesign-part-1-of-2.stl and mydesign-part-2-of-2.stl

The '-o' option can be used to control where the output will be placed. While, the '-of' option can be used to control the format of the output.

You can also provide the parameters to a design by passing -- to the CLI.

jscad mydesign.js --name "Just Me" --title "Geek" -o output.stl

Also, design projects (directories) can be used as the input to the CLI.

jscad myproject/ -o ./test.stl # -- convert the project mydesign to test.stl

Note: The CLI will search for the design entry point just like NPM.

  • if there is a package.json file in the project, then try to load the 'main' property
  • if not, then try to load from 'index.js'

Using the CLI with the JSCAD Examples

The easiest way to use the examples is to create a new NPM project.

mkdir newproject
cd newproject
npm init

Then add both the examples and the CLI to the project.

npm install @jscad/examples
npm install @jscad/cli

And finally, make the examples local to the project.

ln -s node_modules/@jscad/examples ./examples

The examples are just single file designs, or multiple file projects.

npx jscad examples/core/booleans/basicBooleans.js -o ./test.stl
npx jscad examples/module-design/ -of dxf
