Introducing the Designer: Parametric CAD by Clicking, Built for People and Agents

· 10 min read

Until now, making geometry on Bitbybit meant writing it: wiring nodes in Rete, snapping blocks in Blockly or typing TypeScript. Those editors shine when a model is a program, a family of parts generated from a few numbers. But a lot of design isn't programming. You want to draw a profile, pull it into a solid, round an edge, drill four holes and see the result straight away.

The Designer is our answer: a parametric CAD modeller you use with the mouse, in your browser. Draw a sketch, extrude it, fillet it, drill it, then put parts together with joints and pose the assembly. Every step is kept, so changing a size later rebuilds everything that depends on it. The Bitbybit OCCT Kernel does the modelling on your own machine, so there is nothing to install. And because the Designer was built for AI agents as much as for people, an agent can work in the same document beside you, while you keep or undo each of its changes.

The Coding Editors, Rebuilt: Readable Rete Graphs, Async Blockly Functions and a Drone Built Three Ways

· 10 min read
The drone the coding-editor tutorials build, finished in white with orange accents: a carbon frame with hexagon vents, four arms with motors and two-blade propellers, a honeycombed canopy with the bitbybit logo, sprung legs and a camera on its gimbal

Bitbybit has three coding editors: Rete, where you wire nodes together; Blockly, where you snap blocks; and TypeScript, where you write code against the same API. This release rebuilds a large part of all three. Most of the work went into Rete, which now stays readable when a script grows to hundreds of nodes. Blockly functions can await geometry, TypeScript scripts can span many files, and an AI agent can drive any of the three editors.

To show what that adds up to, we built one drone in all three editors: a quadcopter with a carbon frame, motors with cooling slots, propellers that alternate their spin, a canopy traced with a honeycomb and the bitbybit logo on its hatch, sprung landing legs and a camera on a gimbal. Each build is a tutorial with a picture after every step.

Making Bitbybit AI Ready: Our MCP Servers, and a Jet Engine Built With Them

More and more of the code that uses Bitbybit is not typed by a person. It is written by an AI coding agent, inside an editor or a terminal, while a person describes what they want and judges what comes back. We think this is where 3D development is heading, and we want Bitbybit to be the CAD library that agents get right. That is why Bitbybit now runs its own MCP servers: one that teaches any agent the exact Bitbybit API, and one that lets an agent run real CAD operations for you.

To show what that looks like in practice, we asked an agent to build something far beyond a demo cube: a two-spool turbofan engine with 130 unique parts placed 4,853 times, bolted flanges, blades seated in slotted disks, a casing that opens, an exploded view and a welded transport stand. This post explains what MCP is, the use cases we care about most, what they mean for you, and how the engine was made.

The Browser Is the New CAD: From Code to Configurable Products

Matas Ubarevičius at Hannover Messe 2026

In April 2026 Bitbybit travelled to Hannover, where Matas Ubarevičius delivered the presentation titled "The Browser Is the New CAD: From Code to Configurable Products" at Hannover Messe, the world's leading trade fair for the manufacturing industry. The talk was accepted by CAE-Forum for their curated presentation stage and featured in their newsletter. In this blog post he shares his experience from the event and explains why this discourse matters for the manufacturing industry today.

Bitbybit v1.0.0: New Base for Cloud and Web CAD

· 8 min read

Bitbybit v1.0.0

After nearly 100 releases in the 0.x.x range and a release candidate phase, Bitbybit v1.0.0 is officially here. This release brings our new CAD foundation, cloud infrastructure, and an expanded toolkit for developers.

This post outlines the major architectural changes and new capabilities available across our NPM packages, TypeScript SDK, Bitbybit Studio, and the Managed CAD Cloud.

Introducing Managed Bitbybit CAD Cloud with RESTful API

Bitbybit CAD Cloud

Bit by bit developers has always championed the democratization of CAD. The platform empowers users to run complex 3D algorithms directly in the browser - zero installation, zero friction. But as customer ambitions grow, so must the infrastructure.

Today marks the next evolution of the Bitbybit ecosystem: Managed Bitbybit CAD Cloud, powered by a RESTful API.

This is a fundamental expansion designed for enterprise B2B customers who demand more compute power, better IP protection, and scalable workflows than a browser-only environment can provide.

STEP Assembly Support: Load, Parse, and Export Professional CAD Files

Bitbybit STEP Assembly Support

If you've ever tried to load, edit or create a complex STEP assembly in a web browser, you know how tricky it can be. STEP is the standard format engineers use to share CAD models, but browsers don't understand it natively. You usually need desktop software or a server to convert it.

With Bitbybit v1.0.0, that changes. You can now load STEP assemblies directly in the browser, explore their structure, extract individual parts, and export to web-friendly formats. Everything runs locally using Bitbybit OCCT WebAssembly.
