Exporting

SVG

Simple export

Call makerjs.exporter.toSVG(model) passing your model. This function returns a string of SVG.

If your drawing has layers with names that match the following reserved color names, paths on that layer will have a stroke color automatically:
aqua, black, blue, fuchsia, green, gray, lime, maroon, navy, olive, orange, purple, red, silver, teal, white, yellow

Advanced options

There are two main modes of SVG export: Path-only mode and Separate mode. Path-only mode is the default.

In Path-only mode, the SVG structure will have only one SVG <path> element per layer. (If you do not specify layers then you have one "null" layer). This SVG <path> element will contain all of your model's path data. If your drawing contained any closed geometries from endless chains, you will be able to use SVG fill on these shapes.

In Separate mode, every model in your heirarchy is exported as an SVG <g> element containing that model's paths, each exported as an individual SVG element. Lines will export as an SVG <line> element, circles will export as an SVG <circle> element, and arcs will export as an SVG <path> element. Child models will become nested <g> elements. You will not be able to use SVG fill in any satisfactory way.

You may override the default export behavior by calling makerjs.exporter.toSVG(model, options) and passing an options object. The options object has these properties:

property values / effects mode avalability
useSvgPathOnly
  • true (default) - Path-only mode
  • false - Separate mode
accuracy number - Exemplar number of decimal digits (default: .001) Both
annotate
  • true - Adds SVG <text> elements with the path id
  • false (default)
Separate
cssStyle string - CSS style Both
fill string - CSS color (default: none) Path-only
fillRule string - SVG fill-rule (default: "evenodd") Path-only
fontSize string - CSS font size + units (default: 9pt). For annotations and captions. Both
layerOptions object map - keys are the layer names, values are an object with these properties:
property values
cssStyle string - CSS style
fill string - CSS color (default: none)
stroke string - CSS color (default: black)
strokeWidth string - SVG width + units (default: 0.25mm)
Both
origin point - offset your drawing in the SVG coordinate space (default: null) Separate
scale number - scale your drawing (default: 1) Separate
stroke string - CSS color (default: black) Both
strokeWidth string - SVG width + units (default: 0.25mm) Both
svgAttrs object map - attributes to add to the root svg tag Both
units Maker.js unit type (default - extracted from drawing. If unit system is not in drawing or not passed, it will use SVG default of pixels) Both
viewbox
  • true (default) - use SVG viewbox, stretch drawing to fill the SVG element.
  • false - do not stretch drawing
Both

DXF

Simple export

Call makerjs.exporter.toDXF(model) passing your model. This function returns a string of DXF.

Advanced options

Call makerjs.exporter.toDXF(model, options) passing your model and an options object. The options object has these properties:

  • units - Maker.js unit type (default - extracted from drawing. If unit system is not in drawing or not passed, it will use DXF default of inches)
  • fontSize - (default - 9) font size of captions.

OpenJScad

Simple export

Call makerjs.exporter.toOpenJsCad(model) passing your model. This function returns a string of JavaScript code executable within an OpenJsCad environment.

Advanced options

Call makerjs.exporter.toOpenJsCad(model, options) passing your model and an options object.

See the API documentation for OpenJsCad export options
