Synthetic import fixtures
Free DXF and NC1 Sample Files
Use small, legally reusable files to test geometry import and understand CutNesting's fail-closed boundaries. The library deliberately includes valid files, cases that require confirmation, and inputs that must be blocked.

Test-backed library
Expected behavior is part of every sample
A sample is not labeled merely as supported or unsupported. Its manifest records the expected unit state, item outcome, issue codes and, where appropriate, physical dimensions.
DXF
unitless-open-contour.dxf
Unitless open contour is blocked without silent closure
Expected report codes: unit_confirmation_required, parse_failed
File ID: dxf-unitless-open-contour
DXF
unitless-rectangle.dxf
Valid unitless contour requires explicit physical-unit confirmation
File ID: dxf-unitless-rectangle
DXF
unsupported-entity.dxf
Supported boundary plus unsupported source entity requires review
Expected report codes: source_geometry_review
File ID: dxf-unsupported-entity
DXF
self-intersection.dxf
Self-intersecting collision geometry is unsupported
File ID: dxf-self-intersection
NC1
plate-radius.nc1
Plate profile B with supported radius and internal contour
File ID: nc1-plate-radius
NC1
unsupported-profile.nc1
Non-plate DSTV profile is blocked
Expected report codes: parse_failed
File ID: nc1-unsupported-profile
NC1
radius-too-large.nc1
Ambiguous oversized DSTV radius is blocked
Expected report codes: parse_failed
File ID: nc1-radius-too-large
How to use the library
- 1. Choose a focused fixture. Start with one geometry behavior instead of a large production drawing.
- 2. Import it as a part or stock boundary. Confirm units and physical dimensions whenever the drawing is unitless.
- 3. Compare the review outcome. Ready, Needs review and Unsupported are materially different states.
- 4. Keep CAM verification separate. Successful geometry import does not make an exported layout machine-ready.
Test a file in the 2D workspace
CutNesting processes geometry locally in the browser and shows units, physical size, contour warnings and unsupported source entities before adding an item.
