📄️ Introduction

High-performance parametric CAD model generation API. Supports multi-format output (STEP, GLTF, decomposed mesh), pipeline execution, file-based conversion, and async job processing.

📄️ CAD - execute a chained pipeline

Runs multiple operations sequentially. Use '$ref:N' in params to reference step N's result.

📄️ CAD - execute a single operation

Runs a single CAD operation by its fully-qualified identifier.

📄️ CAD - execute compound (parallel) operations

Runs multiple independent operations in parallel.

📄️ Convert - STEP to Draco-compressed glTF (.glb), advanced options

Full-control STEP → glTF conversion with Draco geometry compression. Combines fine-grained mesh, export, and coordinate options with Draco quantization controls. Requires the 'convert' API key scope. Returns 202 with a task ID.

📄️ Convert - STEP to Draco-compressed glTF (.glb)

STEP → glTF conversion with Draco geometry compression using a previously uploaded file. Requires the 'convert' API key scope. Returns 202 with a task ID.

📄️ Convert - STEP to glTF (.glb), advanced options

Full-control STEP → glTF conversion with fine-grained mesh, export, and coordinate options. Requires the 'convert' API key scope. Returns 202 with a task ID.

📄️ Convert - STEP to glTF (.glb)

Simple STEP → glTF conversion using a previously uploaded file. Requires the 'convert' API key scope. Returns 202 with a task ID.

📄️ Files - confirm upload

Confirms that the file was successfully uploaded to the pre-signed URL.

📄️ Files - delete a file

Permanently removes a file and its stored blob.

📄️ Files - get file details

Returns metadata and download URL for a single file.

📄️ Files - list uploaded files

Returns paginated list of uploaded files.

📄️ Files - request an upload URL

Returns a pre-signed URL for uploading a file via PUT.

📄️ Health - status check

Health - status check

📄️ Models - batch-fetch definitions

Returns parameter schemas and defaults for the requested model names.

📄️ Models - build a Dragon Cup

Parametric dragon-scale textured cup with twisted lofted body, voronoi-like skin cells, and configurable shell thickness. All parameters are optional - defaults produce a ready-to-print model.

📄️ Models - build a Phone Nest

Parametric 3D-printable desktop phone holder/stand with a lofted cradle surface, optional ornamental perforations, and a phone mock-up shape. All parameters are optional - defaults produce a ready-to-print model.

📄️ Models - execute a parametric model

Generic endpoint - works for any registered model. See model-specific endpoints for fully typed parameters. Always returns 202 with a task ID for polling.

📄️ Models - generate a batch

Creates a compound task with one sub-task per item. Each item can have different parameters but shares the same output config.

📄️ Models - get parameter definitions

Returns parameter schema, types, defaults, and limits for the specified model.

📄️ Models - list available models

Models - list available models

📄️ Sheet metal - unfold a face, metrics report

Proprietary sheet-metal analysis: computes the unfold metrics report (developability, area, ...) for a single face of an uploaded STEP shape. Requires the 'cad' API key scope. Returns 202 with a task ID; the JSON report is delivered in the task metadata.

📄️ Sheet metal - unfold a face to flat geometry

Proprietary sheet-metal unfold: flattens a single developable face (by index) of an uploaded STEP shape. Requires the 'cad' API key scope. Returns 202 with a task ID; the flattened geometry is delivered as the task's output files.

📄️ Sheet metal - unfold all solids, geometry + report

Proprietary sheet-metal unfold, full workflow: flattens every solid in an uploaded STEP file AND returns per-solid metrics in one call. Requires the 'cad' API key scope. Returns 202 with a task ID; flats are combined into one compound output per format and the per-solid report array is delivered in the task metadata.
