Convert

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.

post/api/v1/convert/step-to-gltf-with-draco

Request body

stepFileIdstring required

ID of the previously uploaded STEP file (returned by the file upload endpoint)

meshPrecisionnumber

Mesh tessellation precision (lower = finer). Range: [0.0001, 10]

meshAnglenumber

Mesh angular deflection in radians. Range: [0.01, π]

meshRelativeboolean

Use size-aware relative deflection per face. When true, meshPrecision is a fraction of each edge's length. Set to false for absolute deflection in model units.

internalVerticesModeboolean

Add interior vertices for better curved face fidelity (slower, set false for speed).

controlSurfaceDeflectionboolean

Extra post-pass refining triangles that bulge beyond the deflection (slower, set false for speed).

  "meshPrecision": 0.1
