2D Nesting Optimizer for Sheet and Plate
Enter simple parts or import irregular contours, match them to real sheet, plate or imported remnant boundaries, then generate a collision-safe visual layout. Material, grade, thickness, clearance and rotation rules stay separate from the 1D bar optimizer.

Step 1
Parts
Enter rectangles or circles. Completing the last row creates the next row automatically.

Step 2
Sheets and plates
Add every available size. Parts only match stock with the same material, grade and thickness.

Nesting rules
Part gap is the finished-part separation required by your process. CAM kerf compensation remains separate.

Separate 2D engine
Irregular geometry
A dedicated Rust/WASM worker nests closed DXF and DSTV plate contours inside rectangular or irregular stock, excluding concavities and voids, without blocking the page.
Safety boundary
Not machine code
Nesting geometry must still be verified for kerf, lead-ins, clamps, defects, machine setup and production safety.
Import safety
DXF and NC1 support matrix
Every drawing is reviewed before it becomes a nestable part or stock boundary. Unitless drawings require an explicit unit and physical-size confirmation.
| Format | Ready support | Review or block |
|---|---|---|
| ASCII DXF | Closed LWPOLYLINE and POLYLINE contours, LINE/ARC chains, CIRCLE, bulges, layers, planar OCS and transformed BLOCK/INSERT geometry. | Open contours, self-intersections, unsupported units, non-planar OCS, ambiguous blocks and unsupported boundary entities must be reviewed or are blocked. |
| DSTV NC / NC1 | Plate profile B, AK outer contours, IK internal contours, grouped BO holes and representable contour radii. | Beam/profile sections, unsupported faces, malformed records and ambiguous or oversized radii are blocked. |
| Output DXF | Validated sheet, void and placed-part polylines in millimetres on named layers. | Not CAM, G-code, common-line cutting, lead-ins, cutting order or machine-specific kerf compensation. |
A reviewable sheet-nesting workflow
Add geometry
Enter rectangles and circles, or import irregular DXF and plate NC1 contours.
Review files
Confirm units, dimensions, layers, contour warnings and whether each item is a part or remnant.
Nest and adjust
Run deterministic WebAssembly nesting, then drag, rotate or lock placements with live validity feedback.
Verify and export
Export job JSON, placement CSV, SVG or nested DXF only after all geometry checks pass.
2D nesting questions
Can I import an irregular leftover sheet or plate?
Yes. Import a closed DXF or supported DSTV plate NC1 contour as stock, classify it as a remnant, confirm any internal voids and set its material, grade and thickness before nesting.
Does the optimizer silently ignore unsupported DXF geometry?
No. Files pass through an import review that shows unit, physical size, warnings and unsupported geometry. Items marked Needs review or Unsupported are not added automatically.
Are nested DXF exports machine-ready toolpaths?
No. Nested DXF files contain reviewed placement geometry in millimetres, not lead-ins, cutting order, common-line cutting, kerf compensation or machine code. Verify every layout in your CAM workflow.
Does my drawing leave the browser?
Nesting, import review and local job storage run in the browser. Optional operational error reporting contains only counts and status codes, never file names, drawing text or coordinates.
