Technical note

How STP and JP2 differ in practice

A 3D model has no front of its own, so the JP2 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 JP2. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one JP2 per part.

3D Workflow

From 3D model to picture

Turn STP models into JP2 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
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Use one angle and size for every model, so a catalogue looks consistent
  • Script the job from the command line for pipelines and scheduled runs

FAQ

STP to JP2 Conversion

What are STP files?

STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
