Standard library and translators

Standard library​

cadflow.stdlib provides parameterized reusable components. The current public inventory includes spur, helical, herringbone, bevel, ring, rack, and cycloidal gear geometry.

from cadflow.stdlib import make_spur_gear_rsolid

gear = make_spur_gear_rsolid(
    n_teeth=24,
    module=2.0,
    pressure_angle=20.0,
    gear_height=8.0,
    backlash=0.05,
)

Gear constructors validate tooth counts, module, pressure angle, height, clearance, and family-specific parameters. They return compatibility solids that can participate in products, recording, serialization, and export. Record the full parameter set; a gear name alone is not enough to reproduce geometry.

See the standard-library catalog for all 13 exports.

Translators​

The Fusion 360 and SolidWorks translators compile supported Model JSON operations into target-oriented scripts. Translator classes expose capability data and structured translation reports; convenience functions return script text or, where supported, orchestrate STEP output through the target application.

from cadflow.translators.fusion360_translator import (
    translate_model_json_to_fusion360_script,
)

script = translate_model_json_to_fusion360_script(
    model_json,
    document_name="CadFlowBracket",
    result_node_ids=result.result_node_ids,
)

Capability boundary​

Translation is operation-aware, not arbitrary source-code conversion. Before delivery:

  1. Inspect the translator capability record.
  2. Use canonical Model JSON with explicit terminal nodes.
  3. Review diagnostics for unsupported or approximated operations.
  4. Run generated scripts only in a controlled target-application environment.
  5. Compare exported geometry and dimensions with the CadFlow source result.

Script generation itself does not prove that the target application version, licenses, add-ins, filesystem policy, or interactive session are available. SolidWorks STEP export has external side effects and should be isolated from pure translation tests.
