Import 3D Model

Status: Implemented

Import 3D Model feature dialog

Import 3D Model loads STL or 3MF data, optionally runs a mesh repair pass, and converts the triangles into a BREP.MeshToBrep solid.

Inputs

  • fileToImport – STL (ASCII or binary) or 3MF data supplied as a string, data URL, or ArrayBuffer.
  • deflectionAngle – face split angle in degrees used when converting the triangle mesh into analytic faces.
  • meshRepairLevel – NONE, BASIC, or AGGRESSIVE passes through BREP.MeshRepairer.
  • centerMesh – translate the imported geometry so its bounding box center is at the origin before conversion.

Behaviour

  • Strings are treated as ASCII STL unless the data begins with a base64 data URL; ArrayBuffers are inspected for ZIP headers (PK) to decide between 3MF and binary STL.
  • When a 3MF file is provided, all meshes in the archive are transformed into world space and merged into a single BufferGeometry before conversion.
  • No timeline or feature history is recovered from the source file—the importer always produces a single solid representing the mesh.
