Technical note

What changes when you convert STEP to JXL

A 3D model has no front of its own, so the JXL 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. STEP 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 JXL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

From 3D model to picture

Turn STEP models into JXL 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

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.
