The whole process
Six phases between the first shot and the file that goes into the machine.
None of the six invents a figure, and the one that cannot resolve a point says so instead of filling it in. Step the player through phase by phase and you will see exactly what Cadmetry knows at each moment — and what it does not know yet.
1. Plantar la estación
El operario deja el DISTO sobre su trípode en un punto desde el que se vean todos los vértices. Ese punto es el origen: todo lo demás se mide respecto a él. Si hay vértices que no se ven, se planta una segunda estación y se enlaza con la primera por una base común.
What is known at this phase
The part nobody explains
A laser meter does not give coordinates. It gives distances.
Everything else is geometry, and it is worth knowing before you trust any measuring program — starting with ours.
When you shoot a corner, the instrument returns a single number: how far it is from itself to that point. With one distance alone, the corner could be anywhere on a sphere around the laser. There is no coordinate to be had from that.
That is why Cadmetry works with three reference positions. You set the same DISTO in three fixed spots — call them A, B and C — and measure the three distances between them. From those three sides the app builds its own coordinate system: it does not need to know where the walls are, or for anything to be square. If A, B and C end up nearly in line they form no triangle, and the app refuses to calibrate rather than hand you bad numbers.
From there, each vertex is measured from all three positions. Three distances cut three spheres: two of them meet in a circle, and the third cuts that circle at two points, one on each side of the A-B-C plane. The engine picks the side — normally the piece is above it — and checks that the three distances agree on the same point within tolerance. If they do not agree, it rejects the point and says so, instead of placing it by eye.
And no angle sensor is involved. No compass, no inclinometer: distances only, because that is the one thing checked to the millimetre against the real instrument. The DISTO's own tilt helps you aim better, but it does not enter the calculation. Fewer sensors in play, fewer ways to get it wrong.
Three reference positions, three radii per vertex, one single point. Checking that all three agree is what separates a measurement from a guess.
Instrument and connection
Your meter, your browser. No drivers and no cable.
Cadmetry does not sell hardware: it talks to the one you already have in the van.
- Reference instrument
- Leica DISTO S910
- Connection
- Bluetooth LE from the browser
- Software on the device
- None
- Devices tested
- Android tablet, Windows PC
- Working unit
- Millimetres
- Without an instrument
- Manual dimension entry
Straight with you: the connection runs over Bluetooth from the browser, and that depends on the device's adapter — on some Windows laptops it plays up, while on an Android tablet it runs a treat. If the meter does not turn up on your first day on site, write to us with the model and the device before writing the trial off.
The export
A DXF the CNC operator understands without ringing you.
Each edge comes out as a line on its finish layer, so you can see at a glance what has to be polished and what stays square — without opening a separate instruction sheet.
Layers by finish
One layer per finish — CANTO_vivo, CANTO_biselado, CANTO_medio_bocel, CANTO_ojiva, CANTO_pulido — plus ESQUINAS_ARCO for the rounded corners, VETA with the angle noted and layer 0 with one point per vertex. Each with its own colour.
Millimetres and real arcs
The header declares millimetres ($INSUNITS = 4), and a rounded corner comes out as an ARC with its centre and its radius, not as a chain of little segments you then have to smooth again in the CAM.
Sheet for the workshop
Besides the DXF, a PDF of the piece to print and leave next to the slab, with the dimensions in plain sight.
Start the trial and generate the first one with your own piece
Around the measuring
Measuring is the engine. The rest is what gets it used every day.
Clients and projects
Every piece hangs off a project, and every project off one of the workshop's own clients, with its material and its history.
Calendar
Survey and installation visits, in a calendar the workshop shares.
Attachments in Drive
Photos and drawings are kept in the workshop's own Google Drive, connected by OAuth just once. Cadmetry does not hold on to your files.
Roles
Workshop administrator and operator, with different permissions: whoever does the measuring has no need to see the billing.
Billing
Monthly subscription with a PDF invoice, VAT worked out according to the client and a warning before every charge.
Cutout templates
The sinks and hobs you fit most, saved with their sizes so you never type them in again.
So there are no surprises
What Cadmetry does not do, and is not going to do.
We would rather tell you here than in the third week of the trial.
It does not optimise cutting on the slab
There is no nesting: Cadmetry does not decide how to fit your pieces on the slab to save material. That is a product decision, not a gap waiting to be filled. Your CAM goes on doing that work.
It does not design the kitchen
It is not a furniture configurator or a 3D renderer. It starts where the kitchen is already fitted and the real opening has to be measured.
It does not replace your CAM
It generates no machine code and no tool paths. It hands over clean, dimensioned geometry; the post-processor is still yours.
The cutouts do not travel in the DXF yet
The sink and the hob are dimensioned in the app and saved with the piece, but today the DXF comes out with the contour and the edges, not with the cutouts. They go separately, and we say so here instead of letting you find out when you open the file.
It does not measure on its own
Somebody has to point the laser at each vertex. There is no automatic scanning of the room and no photogrammetry.
Fancy trying it on a real piece?
Ten days, your DISTO and a worktop you have already measured. Compare.
