Module dispatch 

ONE entry point over every strategy: the generator the application’s worker calls per operation, without knowing which lane wrote the strategy or what inputs it takes.

Each lane’s generate has its own signature — the drop-cutter finishes take a cutter, heights and feeds; the waterline family takes the setup, the tool and its limits; the 2.5D family a PlanarInput of regions; drilling the recognised holes — so this module builds those inputs from the operation, the setup, the document’s tools and the mesh snapshot, and dispatches exhaustively on the strategy. Advanced model inputs arrive in GenerateContext; missing geometry is a named refusal, never a guessed path. Pattern expansion preserves program sections through generate_expanded.

Hole recognition needs the kernel (the adapter’s revolved faces), which lives on the worker side; the caller recognises holes there and passes them in, so this module stays kernel-free.

Modules

chains

Identity-based chain extraction. Geometry is supplied by the worker; mesh silhouettes cannot recover persistent edges or sketch geometry.

Structs

GenerateContext

Additional model data that cannot be reconstructed safely from triangles. The worker resolves these by identity; no arbitrary previous path is chosen.

GenerateInput

What one operation’s generation reads.

TurningInput

Geometry supplement supplied by the model adapter/feature selection. A supplied profile must include all protected axisymmetric material. Otherwise the public extractor builds it from adapter-certified carriers and the mesh.

Enums

MillTurnInput

Live-tool selection is distinct from Strategy: the shared model has no polar/cylindrical strategy variants. Inputs are explicit compensated CL contours and separated rotating/fixed meshes, as required by C11’s API.

Functions

feeds_of

The feeds an operation cuts at: its own override, else the tool’s.

generate

Generate one operation’s toolpath.

generate_expanded

Pattern output retains separate operations/tools/WCS sections. The single Toolpath API refuses this loss of information; workers use this entry point for program expansion and pass its setups to program::assemble.

generate_with_context

Generate with resolved model inputs. Existing single-operation arms are unchanged.

heights_of

The heights an operation cuts at: its own override, else the setup’s.

planar_input

The 2.5D input for an operation: one planar region per drive face (its projected outline, at the face’s top) and, for an operation with no drive faces, the targets’ silhouette (the projected union of every triangle, at the body’s top); the stock top at the mesh’s top. Nothing to outline is the model’s empty-target error.

tool_of

The operation’s tool, from the document’s tools.
