Technical note

STP to JXR: what carries over and what does not

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

3D Workflow

From 3D model to picture

Turn STP models into JXR 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
  • Draw isometric, top, front or side views as line drawings with 2D projection

FAQ

STP to JXR 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 JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
