Introduction
The Designer is Bitbybit's interactive CAD modeller. Make parametric parts and assemblies by clicking, work beside an AI agent in the same document, and export STEP, GLB or STL.
A tour
The Designer's window part by part - the menus, the toolbar, the Features panel, the view with its view bar and cube, Properties, the dock and the status bar - and where to find a command, a tutorial or a realistic look.
Showcases
Three projects modelled in the Designer - a six-axis robot arm with four poses, a turbofan engine that opens and explodes, and the desk arm of the tutorial - with what each one shows, to open in the Designer or download.

How it works
The ideas behind the Designer - documents, features built in order, sketches, parameters and expressions, references that survive edits, parts, and assemblies with connectors and joints.

Working with agents
How an AI agent works in the Designer beside you - the tools it uses, how you see it working, how you keep or undo each of its changes, and whose camera its views move.
