How you design with AICAD-X

Type it in plain English — "design a box with a lid", "a wall bracket for a 5 kg shelf", "a quadcopter frame for 5-inch props".

• No CAD knowledge needed. Say what it is, roughly how big, and what it is for.
• Attach reference photos if you have them — the AI reads them with its vision model.
• Once a design exists, circle an area on the viewport and say what to change in chat.

Before it designs, the engineer asks one to four short tick-box questions written for your request, with its recommended pick already ticked.

• Typical questions: what is it made of (moulded plastic, wood, sheet metal), rough size, what goes in it, hinge or latch style.
• Each answer changes the engineering — sheet steel becomes a bottom plate plus four wall panels; moulded plastic becomes one hollow shell.
• Not sure? Press "You choose" and the AI proceeds with its own recommendations.

The engineer turns your request and choices into a brief: every component and quantity, how each is formed, how it is constructed, what joins what, and the materials.

• A box in sheet steel: bottom plate + 4 wall panels, a plate lid, 2 hinges bridging body and lid, M4 through-bolts with nuts because 3 mm steel is too thin to tap.
• The brief is a contract — the build is checked against it, so a component cannot silently go missing or change form.

The AI writes a compact build program and runs it in its own Blender sandbox. Parts appear in your viewport as they are created, seated and fastened.

• Standard fittings — hinges, brackets, latches, motors, propellers, connectors — come from an engineered parts library with real mounting patterns.
• The sandbox drills the parts a fitting mounts to and seats the AI-chosen screws, bolts, nuts or rivets as real parts.
• Anything wrong is reported back to the AI, which repairs its program and tries again — you see each round in the event stream.

The editor looks like a CAD editor — viewport, Model Tree, Inspector — but it is read-only. You look; the AI does the CAD work.

• Model Tree: every part, including each screw and nut, arranged by what it is mounted on.
• Inspector: click a part to see its material, size in millimetres, what it is mounted to and its position.
• Viewport: orbit, zoom, Faceted / Smooth / Wireframe display, exploded view — all display modes, never edits.

Every design is checked before it is handed to you. The results stream into the chat in plain language, not error codes.

• Fit: parts sit flush on what they mount to (gap 0.000 mm), panels meet at the edges without overhang.
• Collisions: no part passes through another; touching faces and mated pairs are allowed.
• Mounting and joins: a hinge must really touch both the body and the lid; fasteners must reach through both leaves.
• Materials: the built part uses the material the brief chose.

A hinged lid, door or flap is swung about its real hinge pins in the sandbox: does it clear the rim, do the hinges stay attached, does it close flush?

• When the design completes, the motion plays once in your viewport; press "Play motion" to watch it again.
• The lid-side hinge leaves and their bolts swing with the lid, so you see inside the hollow body.
• If a mechanism does not work, the design fails honestly and says why ("hinge is turned the wrong way round…").

A finished design gives you STEP files for every part plus a placed assembly STEP, a GLB for the web or AR, and a rendered image — all under the Export button at the top of the viewport.

• STEP is the industry exchange format — open the files in any CAD package, send them to a machine shop or a 3D-print bureau.
• Every screw, nut and hinge is in the assembly STEP at the position it was fitted.
• The GLB is the same model you see in the viewport — use it for web previews or AR/XR review.
