Draw in 2D or in 3D. It is the same drawing.
2D and 3D are not two screens someone has to keep in sync: they are two views of the same document. The selected stone, the dimension — an editable field in both —, the cutout and the drag behave identically on either side. And the geometry that comes out is assembly geometry, not illustration: vertices are stored to the thousandth of a millimetre and an arc reaches the DXF as an arc.
2D and 3D are one truth
There is no second model to maintain. The stone lit in 2D is lit in 3D, the dimension is a typeable field in both views, the cutout opening is clickable in 3D just as the polygon is in 2D, and dragging a stone is the same gesture — same snap, same undo. You pick the view for convenience, not because the task forces you.
CAD commands, in stone-shop vocabulary
Point-by-point pen, rectangle, circle by radius, draggable vertices and edges, tape measure, typeable dimensions, per-corner angles and rounding. The commands a CAD drafter already knows are there: rectangular, polar and path array, offset of the whole outline or of a single edge, mirror, rotate the whole selection, and group. An optional command line (the / key) accepts AutoCAD aliases — REC, PL, CI, F, O, AR, MI — with the number included: REC 120x60 draws right away. None of it has to be memorised: every tool sits on the side rail, and they all speak in top, apron, backsplash, return, build-up, cutout and sink.
Vertices to the thousandth of a millimetre
Full precision inside, rounding only on screen: the dimension shows one decimal while the drawing keeps the number the maths produced. A typed value stays exact and is never quietly adjusted behind your back. A micrometre is ten times finer than any CNC's resolution, and the DXF still writes three decimals.
Angle handling, including the error nobody sees
The angle tool reads each corner to three decimals — that is the decimal where you see that 89.99° is not 90°. Type 90 into one corner and both corners on that side close together — correcting one does not throw off the other, which is the classic failure of squaring a shape by dragging vertices. And one guard matters more than the feature itself: the angle tool never changes a length — any write that would move a dimension beyond tolerance is refused, not silently corrected.
Round by dragging, and a curve the machine understands
Drag a corner inwards and it rounds; the second corner snaps to the first one's exact radius, which is how four matching corners are set without typing a radius at all. The arc is a property of the edge, never extra vertices: the drawing keeps the curve and it reaches the DXF as a real curve, not as a run of straight segments that resembles one. A curved apron is faceted from the shop's real grinding allowance, editable edge by edge, and finer facets never change the price.
A finish is geometry, not a label
22 edge profiles, 5 joint models and up to 2 build-ups per edge, and choosing one name settles all three at once, with no invalid combination to memorise. The joint moves the stone: flush, mitre, reveal, raised and recessed put the panel in different places and send different cuts to the saw. A 20 mm slab with a 30 mm build-up gives a 50 mm band, and the band is derived, not typed.
Every surface is a stone, not a field
Apron, backsplash, splash rail, return, segment and build-up each have their own outline and hang from the edge that hosts them. That is what 'add an apron' cannot do: an apron on half the front, a stretched strip, strip over strip, an upright piece, stone laminated onto stone — charged per square metre — and edge-to-edge seams charged per linear metre.
Cutouts dimensioned like technical drawings
Rectangle with corner radius, circle by diameter and two-axis ellipse — the drop-in basin —, on any surface of the piece, not only the top. Dimensioning follows drafting practice: one dimension per axis, from the nearest edge, ending at the centre mark. When the path to the edge crosses another hole, the measurement becomes centre-to-centre, which is how a tap battery is marked without two lines printed on top of each other.
From the first line to the machine file
Five steps, and none of them retypes the piece. What changes from the first to the last is only the question being asked of the same document.
Draw the outline
Rectangle by dragging, free outline point by point with the pen, or one of 5 ready projects: niche, column, L-shaped bathroom top, L-shaped kitchen top and barbecue opening. A ready project is a birth recipe — after the click they are ordinary pieces, editable one by one.
Check dimensions and angles
Measure on screen, type the exact value and check every corner with the angle tool. When the figure has accumulated half a millimetre of slack, snapping the dimensions brings them all to the displayed value at once — as an explicit act, because geometry must not change by itself the night before cutting.
Hang the surfaces
Apron, backsplash, return, segment and build-up are born on the edge that hosts them, each with its own height and overhang. Every edge can have one, and none has to.
Pick one finish per edge
One name settles the corner profile, the joint with the neighbouring piece and how many layers are glued. Corner mitres and in-plan seams are derived by the engine: nobody types the angle.
Approve and send it to the shop
The price followed every line along the way. At approval the cut map freezes, and the same document produces the shop-floor sheet, the slab nesting plan, the DXF and the customer's 3D link.
The same drawing becomes four documents.
Price with an address
The slab is charged by surface: one line for the top and one per strip, addressed to its edge. Every square metre can be traced back — the backsplash's area is not buried in a total.
Frozen cut map
One stone per line, with outline, dimensions, positioned cutouts and only the marks that change the work: polishing and mitres. A sheet where everything is marked marks nothing.
DXF in millimetres
The same stones as the map, in millimetres, with arcs as arcs and operations split by layer for the CAM to read.
3D in the customer's hand
The same document, with the real texture of the chosen slab, opened from a temporary link with no app and no account.
Questions about drawing and design
- Can I draw in both 2D and 3D in the same project?
- Yes, and they are not two files. 2D and 3D are views of the same document: selection, editable dimensions, cutouts and stone dragging behave the same in both. There is no export from 2D to 3D and no second version to maintain — the 3D is derived from the drawing, not modelled again.
- Do I need to know AutoCAD to use it?
- No. Every tool sits on the side rail and speaks in tops, aprons, backsplashes, returns, build-ups, cutouts and sinks; a corner is rounded by dragging it. People coming from AutoCAD find the commands they already use — array, offset, fillet, mirror — and an optional command line with the same aliases (REC, PL, F, O, AR). People who have never used CAD draw from the buttons, memorising nothing, with the same precision.
- How precise is the drawing that reaches the machine?
- Vertices are stored to the thousandth of a millimetre and rounded only for display. A typed value stays exactly as typed; only the hand-gesture snap rounds to the millimetre. In the DXF coordinates are written with three decimals and an arc leaves as an arc, in the format's own polyline convention — not as a polyline that merely resembles the curve.
- How does the system handle angles?
- Every corner has an angle read and edited to three decimals. Typing an angle corrects the figure by spreading the slack across all edges, which is why both bottom corners close at 90° at the same time instead of one correction throwing off the other. What the screen shows as square stays square. And the angle tool never alters a length: any write that would move a dimension is refused.
- Can I make rounded corners and curved aprons?
- Yes, without typing a radius: drag the corner inwards and it rounds; the next one snaps to the same radius. A curved edge is already quoted by arc length rather than by the straight line. For a curved apron the engine facets from the polisher's real grinding allowance rather than from screen resolution: it is how many segments the machine can actually close, editable edge by edge, and finer facets never change the price.
- What can I draw beyond a rectangular countertop?
- Free outlines with any number of vertices, arcs, upright pieces, strip over strip (the niche), an apron on half an edge, containment edges, carved sinks with a ramp and drainage channel, American and Italian recesses, and parametric fluting whose last slat is trimmed by the outline. That is 7 parametric processes and 5 ready projects, and after the click everything stays editable piece by piece.
- Does Marmos replace my CNC's CAM?
- No, and that matters: the DXF carries nominal geometry and fabrication intent split by layer. Tooling, kerf compensation, depth, lead-in and final ordering stay in the CAM and in the machine's approved post-processor. Format compatibility is not a substitute for testing on the real machine before the first production cut.
