DSTV/NC1 Plate Import Supported Subset

CutNesting supports a deliberately narrow flat-plate subset. NC1 also describes beams, channels, angles, tubes and face-specific operations; silently flattening every file into a sheet part would create unsafe geometry.

ASCII NC and NC1Plate profile B onlyFail-closed import review

Supported plate boundary

  • ASCII `.nc` and `.nc1` files, normally one plate part per file with multi-file batch selection.
  • Plate profile type `B` only, with useful identifier, material and thickness metadata when unambiguous.
  • `AK` outer contours and `IK` internal contours that form safe planar rings.
  • Grouped `BO` holes represented as internal void geometry.
  • Representable contour radii after radius and tangent validation.

Explicitly outside the subset

  • I, U/C, L, tube, bar, T, Z and other structural profiles.
  • Curved beams, automatic unfolding and ambiguous face-coordinate interpretation.
  • Backside or bevel data that changes the safe planar boundary.
  • Marks, hard stamps and powder lines treated as cutting geometry.
  • Malformed records, unsupported faces and ambiguous or oversized radii.

Import review

Parsing is only the first gate

A recognized block does not automatically become nestable geometry. The browser review pipeline validates the complete planar result.

1

Profile gate

Confirm the file describes a flat plate profile B.

2

Record parsing

Read supported contour and hole blocks without silently accepting malformed data.

3

Geometry checks

Validate radii, ring closure, area, self-intersection, containment and physical size.

4

User review

Show Ready, Needs review or Unsupported before a part or remnant is added.

Three focused NC1 fixtures

The public sample library includes one accepted plate and two expected rejections. Negative fixtures document the safety boundary rather than weakening it.

View every DXF and NC1 sample

Ready

plate-radius.nc1

Plate profile B with a supported radius, internal contour and grouped hole.

Blocked

unsupported-profile.nc1

A non-plate structural profile is rejected rather than treated as a flat outline.

Blocked

radius-too-large.nc1

An ambiguous oversized contour radius is rejected rather than approximated silently.

NC1 import is not CAM output

CutNesting creates reviewed nesting geometry. It does not generate lead-ins, pierce order, common-line cutting, machine-specific kerf compensation, G-code or controller-ready programs. Verify every layout in the normal engineering and CAM workflow.
