Technical note

STEP to DCM: what carries over and what does not

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

3D Workflow

Convert 3D models in batch

reaConverter converts STEP models to DCM offline and in batch, without Blender or a CAD licence.

  • Convert a whole folder of models to DCM in one run
  • Draw isometric, top, front or side views as line drawings with 2D projection
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

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.
