Technical note

Before you convert STP to JPEG

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

3D Workflow

From 3D model to picture

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