CAD that talks back.

Send it to the printer, or to the shop.

Most parts stop here. File ▸ Export gives you what a slicer or another CAD package needs, and one press of Output ▸ Drawings turns the model into a drawing you can hand to someone.

• STL for 3D printing, tessellated only at export, at the resolution you choose in the dialog (or the agent picks a tolerance). One file for everything or one per body, so multi-part prints come out as separate meshes.
• Slice without leaving the app: if OrcaSlicer (or Bambu Studio) is installed, set your printer, filament, layer height, infill and supports once in Settings, hit Output ▸ Slice, and the layers appear in the viewer with a slider, feature colours, time and filament estimates, plus G-code and 3MF. Or just say “slice this for my Ender 3 at 0.28 mm”.
• STEP, exact: cylinders stay cylinders and bodies stay separate solids, so it opens cleanly in Fusion, FreeCAD, SolidWorks or a supplier's quoting tool.
• Shop drawings from the exact model: third-angle front, top, right and iso with hidden lines, overall dimensions, hole callouts and a lettered hole table, title block with mass and scale. SVG and DXF.
• Ask for it: “export an STL at 0.05 mm for the Pin only” or “make drawings in aluminium” works too, because export and drawings are agent tools.

The agent extends the app itself.

Ask for a mass-and-cost estimator, a bolt-pattern tool, a thin-wall check or a hole report, and the agent writes one Python file. It can add helpers every design script can call, tools the agent itself can call, checks that run after every build, and panels: sliders, numbers, pickers that take a face or a body from the viewer, tables whose rows select the geometry they describe, buttons. Panels are declared, not coded, so they render from the toolbar's Extensions menu with the app's own look and keep working across releases. Files hot-reload; Settings lists them, and a broken one shows as broken instead of breaking a design.

@panel("Round corners", icon="◜", description="Fillet the vertical edges of a body")
def round_corners(ctx):
    s = ctx.state
    body, radius = s.get("body"), s.get("radius", 2.0)
    info = ui.text("Pick a body in the viewer.", muted=True)
    if body:
        b = ctx.body(body)
        info = ui.kv([["Body", body], ["Vertical edges", len(_vertical_edges(b.shape))]])
    return ui.panel(ui.picker("body", "Body", what="body"),
                    ui.slider("radius", "Radius", radius, 0.5, 6, step=0.5, unit="mm"),
                    info, ui.button("Apply", call="round_corners_apply", primary=True))

That is the panel in the clip, as the agent wrote it during the recording (lightly abridged); its Apply wraps the body in a round_vertical_edges(plate, 3) helper it also defined. Built-in examples ship with the app: Parameters (every number as a live slider), Hole report, Bolt pattern.

Then run it, one checked step at a time.

The Machine workspace connects to a Makera Z1 on your network: the status strip, the camera with a jog pad, and four steps. Prepare: home, change tool (the machine's own change, every tool and probe measured on the setter, the packet photo on the card). Zero: what the setup wants next to what set the origin this session; Find the block probes three corners of a block in the L-bracket and puts X0 Y0 on the front-left from the measured faces; on a rotary setup Zero on the 4th axis runs Makera's own 4th-axis Z probe for Z0 on the chuck centreline, sets Y0 from the controller's rotation offset, A0 and X0, one confirmed step at a time, with A on the DRO and the jog pad. Run: a readiness checklist, the program's operations in tool runs, an air cut first, progress op by op. Manual for everything else.

The assistant can work the machine too: hold, pause and STOP act at once; everything that moves waits as an approval card until you click Approve. Every spindle start lifts first, moves over the work, then comes down.

Watch a session, step by step.
