How It Works

Technical note

How FBX and CAL differ in practice

A 3D model has no front of its own, so the CAL shows it from one viewpoint: the angles you set on the X, Y and Z axes, or a preset such as the isometric view. Whatever faces away from that viewpoint is not in the picture, so a part with features on several sides needs several images, which the multiple-frames option renders in one run. FBX describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the CAL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

From 3D model to picture

Turn FBX models into CAL 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
  • Use one angle and size for every model, so a catalogue looks consistent
  • Script the job from the command line for pipelines and scheduled runs
  • Draw isometric, top, front or side views as line drawings with 2D projection
