A tour of the Designer

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.

Components and sub-assemblies

Place parts in a Designer assembly as components, give each its own sizes, place whole assemblies as sub-assemblies, move a component, and open the document a component comes from to change it.

Connectors

Mark where a Designer part attaches with connectors - on a flat face, on a hole's or a cylinder's axis, or at a circular edge's centre - and give a hole of several positions one connector per hole.

Create a Designer project

Start a new project whose first script is a Designer script, in the cloud or in this browser, or add a Designer script to a project you already have.

Designer commands

Every command in the Designer: what it does, where to find it in the menus or toolbar, its key, the values it takes, and the name an agent runs it by.

Designer keyboard shortcuts

The Designer's keyboard shortcuts on Windows, Linux and macOS, each with the command it runs, taken from the commands themselves so the list is never out of date.

Designer tools for agents

The tools the Designer offers AI agents while it is open: reading documents and builds, running any command, applying patches, selecting, locating, capturing the view and undoing.

Export and import design files

Save a whole Designer project or one document as a file - project, project with geometry, design document, STEP, GLB, BREP or STL - and bring design documents or CAD files back in.

Features and their dialogs

Every feature the Designer adds to a part - solids, extrudes, revolves, sweeps and lofts, fillets, chamfers, shells, holes, bosses and pockets, booleans and patterns - and how their dialogs take values, picks and expressions.

Getting Started Overview

What bitbybit.dev offers and where to begin - projects and scripts, the Rete, Blockly and TypeScript coding editors, the Designer, the open-source packages, CAD Cloud, 3D Bits for Shopify and the model configurators.

How the Designer 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.

How your work is saved

The Designer saves as you work - in this browser at once and in the cloud a few seconds later - with File > Save to send it now, a status beside the script's title, a history to restore from, and cloud backups.

Inspect an assembly: parts list, clashes and mass

Check a Designer assembly - the bill of materials that counts every part through every level, the clash check that finds parts that overlap or come too close, and the volume and mass of each part.

Joints

Join Designer components by their connectors - fastened, turning, sliding or both - set the angle or offset and the limits, drive a joint by a parameter, and pose the assembly with configurations.

Make your first part

A first Designer tutorial - a mounting plate made from three parameters, a sketch, an extrude, rounded edges and four holes, then one change of a parameter that the whole plate follows.

Model a desk robot arm

A longer Designer tutorial in nine chapters - eight parametric parts, from a revolved base to a serrated gripper jaw, brought together in an assembly with joints, limits and fasteners replicated onto every hole, with a picture of every step.

Model a desk robot arm: the assembly

The last chapter of the desk arm - an assembly with a parameter per joint, the parts inserted (both links from one document), revolute and slider joints with limits, and the screws and nuts replicated onto their holes.

Model a desk robot arm: the base

The first chapter of the desk arm - a pedestal revolved from half its section, four counterbored holes in its ledge, its material, and the two connectors where the shoulder sits and its screws go.

Model a desk robot arm: the gripper

The fifth chapter of the desk arm - the gripper's palm with two pocketed jaw rails, four counterbored cover screws, and a neck blended into the palm, with connectors for the wrist, both jaws and the screws.

Model a desk robot arm: the jaw

The sixth chapter of the desk arm - a serrated finger drawn as one profile, a carriage that rides in the gripper's rail, two screw holes and the connector it slides on.

Model a desk robot arm: the link

The third chapter of the desk arm - one link document with five parameters, whose waisted side, forked hub, lightening window and pivot holes all follow them, so the arm uses it twice at two sizes.

Model a desk robot arm: the nut

The eighth chapter of the desk arm - a hex nut parametric in its diameter, chamfered on both sides, for the bolts through the arm's three pivots.

Model a desk robot arm: the screw

The seventh chapter of the desk arm - a socket-head screw parametric in its diameter and length, so every bolt and screw in the arm is this one document at its own size.

Model a desk robot arm: the shoulder

The second chapter of the desk arm - a clevis cheek extruded, given a hub and rounded, mirrored into a pair, and joined to a revolved drum, with the pivot hole and four connectors.

Model a desk robot arm: the wrist

The fourth chapter of the desk arm - a knuckle that turns in the forearm's fork, with a tool flange raised on its face, rounded rims, the pin hole and two connectors.

Open a design again

Find a Designer script in My Projects and open it, open someone else's public design, what happens to the changes you make to it, and what a plan below Gold sees.

Open the Designer

Three ways into the Designer on bitbybit.dev - the Apps menu, the start dialog and My Projects - and how a plan below Gold views a design someone shares.

Parameters and expressions

Name the sizes that matter in a Designer part or assembly, write other numbers as expressions of them, drag a slider to see the model follow, and keep sets of values as configurations.

Parts and materials

Turn a Designer body into a part - give it a name, a material from the presets, a colour and a finish - and read the volume and mass the Designer works out from its geometry and its material's density.

Patterns of components

Place copies of a Designer component around an axis or along a direction, such as a row of fan blades, with the count and spacing written as expressions and every copy counted in the bill of materials.

References to faces and edges

How a Designer feature names the faces and edges it works on, why those names survive changes to the part, what happens when a change takes a face away, and how to point the feature at another one.

Replicate: a part on every hole

Place a Designer component on every connector of a set in one step, such as a screw in every hole of a flange, so the copies follow when holes are added, moved or taken away.

Share a design

Share a Designer project by its visibility, its link, a preview or an embed, or by sending the project file - who can view it, who can change it, and what visitors may download.

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.

Sketches

Draw a sketch in the Designer - pick a plane or a flat face, draw with the sketch bar's lines, arcs, rectangles, circles and polygons, round or bevel corners, and edit every point later as an expression.

The Designer

The Designer is bitbybit.dev's parametric CAD modeller on the Gold plan - parts and assemblies made by clicking instead of code - and where its own documentation starts.

The Designer: parametric CAD by clicking

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.

The view, picking and panels

Move around a model in the Designer, look from a named side, pick faces and edges with the right pick mode, use what the Selection panel offers for your picks, and arrange the panels to suit you.

When a build has problems

What the Designer's Problems tab tells you when a feature cannot be built, how a failure carries through the features after it, and what to do - edit, undo, suppress, copy the problem or send a crash report.

Working with agents in the Designer

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.
