Technical note

STP 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. STP 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 DCM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

3D Workflow

Convert 3D models in batch

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

  • Convert a whole folder of models to DCM in one run
  • Script the job from the command line for pipelines and scheduled runs
  • Set the camera angle on X, Y and Z, or start from the isometric preset

reaConverter handles STP file conversion excellently. The batch processing feature is perfect for converting multiple CAD files at once, and the drag-and-drop interface makes it super easy to use. Quality is preserved well during conversion, and it supports plenty of output formats. Recommended for engineers and designers.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.
