Import & Export


The graph supports a limited set of geometry and image formats for import and export.

Imported geometry and images files need to be uploaded as assets before they can be used.

Images

Images are primarily used as textures for materials.

The following two formats are supported for upload:

  • JPEG / JPG
  • PNG

An image that was previously uploaded in one of these formats, can be loaded into a graph using the image asset node.

See the material concept page for more on working with images as textures.

Geometry import

The following formats are supported for import, with noted limitations:

  • IGES: NURBS curves (126), patches (128), polylines (106) - no trimmed patches
  • Wavefront OBJ: vertices, faces, groups, but no normals, nor UVs
  • DXF: POLYLINE entity type only

Geometry that was previously uploaded in one of these formats, can be loaded into a graph using the geometry asset node.

Geometry export

Geometry can be exported from the graph by either:

  • Right mouse button clicking a node, navigating to Download, and selecting a file format.
  • Right mouse button clicking the graph background, navigating to Download all outputs, and selecting a file format.

The latter option will download the geometry from all output selected nodes.

IGES

Exports following primitive types and properties:

Wavefront OBJ

Exports following primitive types:

Exports:

  • Vertices
  • Faces: 1 per triangle
  • Groups: 1 per primitive
  • Normals
  • UVs if available

STL

Exports following primitive types:

ASCII STL only. STLs only contain triangle data. No normals, UVs, or groups.

DXF

Exports following primitive types:

Note that the curves only support 2D coordinates: XY, with Z coordinate effectively zeroed.

TRB

Exports following primitive types:

Exports:

  • Vertices
  • Faces: 1 per triangle
  • Groups: 1 per primitive
  • UVs if available
