3D Workflow

From 3D model to picture

Turn STP models into SGI previews without opening a 3D program. Set the angle once, and every model in the folder is rendered the same way.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Raise the level of detail for smooth curves on close-ups
  • Split an assembly with Load STEP as separated shapes to get one picture per part
  • Draw isometric, top, front or side views as line drawings with 2D projection
