Maker.js: Parametric CNC Drawings Using JavaScript

Microsoft recently open sourced, twenty five days ago, Maker.js — a JavaScript library to create drawings on the browser for CNC and laser cutting.

I love the playground site they made to share parametric scripts (say, of a smiley face, a hello, world text, a floor plan, and more). See all demos.

From their website:

• Drawings are a simple JavaScript object which can be serialized / deserialized conventionally with JSON. This also makes a drawing easy to clone.
• Other people's Models can be required the Node.s way, modified, and re-exported.
• Models can be scaled, distorted, measured, and converted to different unit systems.
• Paths can be distorted.
• Models can be rotated or mirrored.
• Find intersection points or intersection angles of paths.
• Traverse a model tree to reason over its children.
• Detect chains formed by paths connecting end to end.
• Get the points along a path or along a chain of paths.
• Easily add a curvature at the joint between any 2 paths, using a traditional or a dogbone fillet.
• Combine models with boolean operations to get unions, intersections, or punches.
• Expand paths to simulate a stroke thickness, with the option to bevel joints.
• Outline model to create a surrounding outline, with the option to bevel joints.
• Layout clones into rows, columns, grids, bricks, or honeycombs.
