Python tool that finds drawings resembling a hand sketch, photo or MS Paint
outline. It indexes the OpenNest server's drawing library (read-only) and/or
DXF folders, compares DINOv2 embeddings of normalized renderings across all
8 rotations/mirrors, and writes an HTML page of the closest matches with an
optional overall-size filter.
train.py fine-tunes the embedding contrastively on synthetic sketches of the
library itself (no labelling); evaluate.py measures recall on held-out
drawings or a folder of real sketches. On 40,757 server drawings, held-out
synthetic sketches find the right shape in the top 20 75% of the time,
up from 18% zero-shot.

Reading a nest used to fill the engine's static BestFitCache as a side
effect, which is the only reason OpenNest.IO referenced OpenNest.Engine.
Core now defines SavedPairSet/SavedPairResult and IBestFitStore; the
mapping to BestFitResult moved verbatim into Engine's BestFitCacheStore.
NestReader/NestWriter take the store as an optional BestFitStore property
and skip bestfits/ entries without one.
Every production reader and writer opts into BestFitCacheStore.Shared, so
behaviour is unchanged; the golden round-trip test still matches byte for
byte.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
ACadSharp already includes DwgReader, so this wires it up across the
entire import pipeline — Dxf.Import, CadConverter drag-drop, nest
import dialog, console CLI, BOM analyzer, and training data collector.

Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Drawings created by BomImportForm and MCP InputTools were missing color
assignments, causing them to render with default empty color instead of
the standard part color palette. Moved PartColors and GetNextColor() to
Drawing in Core so all consumers share one definition.

Etch marks for up bends are now real geometry entities on an ETCH layer
instead of being drawn dynamically. They flow through the full pipeline:
entities → FilterPanel layers → ConvertGeometry (tagged as Scribe) →
post-processor sequencing before cut geometry.
Also includes ShapeProfile normalization (CW perimeter, CCW cutouts)
applied consistently across all import paths, and inward offset support
for cutout shapes in overlap/offset polygon calculations.

Kept using OpenNest.Api in Timing.cs and EditNestForm.cs alongside
remote's reorganized usings and namespace changes.

Add FileExtension and FileFilter constants to NestFormat and update all
references across Console, MCP, Training, and WinForms projects.

Move brute-force data collection, TrainingDatabase, and GPU init from
OpenNest.Console into a dedicated OpenNest.Training project. Replaces
raw Microsoft.Data.Sqlite with EF Core. Console is now a pure nesting
CLI with template support and cleaned-up usage output.
