Technical note

What changes when you convert STEP to AVIF

A 3D model has no front of its own, so the AVIF 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. Without further settings, a STEP assembly converts to a single AVIF. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one AVIF per part.

3D Workflow

From 3D model to picture

Turn STEP models into AVIF 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
Keep unreleased designs and client models on your PC: nothing is uploaded
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
