Technical note

Before you convert STEP to WEBP

A 3D model has no front of its own, so the WEBP 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 WEBP. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one WEBP per part.

3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not STEP files. reaConverter renders each model to WEBP at the angle you set, a whole folder at a time.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Script the job from the command line for pipelines and scheduled runs
  • 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

I needed to convert a batch of STEP files for a client presentation and ReaConverter made it simple. The interface is intuitive, letting me drag, drop, and choose my output format (I used STL) in seconds. The batch processing saved me hours of work. Highly recommended for its reliability and speed.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
