Technical note

How PCX and STP differ in practice

PCX is made of pixels, so the conversion works in two steps: the image is first traced into vector outlines, and those outlines are then extruded to the height you set. The result is real geometry rather than a picture wrapped in a 3D file. Outline tracing is the mode to use here, because it returns closed shapes, and only a closed shape has an area to lift. How good the result is depends almost entirely on the PCX going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

3D Workflow

From picture to 3D model

Need a 3D STP from a flat PCX image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Pick up new models automatically with Watch Folders

FAQ

PCX to STP Conversion

What are PCX files?

The PCX (Personal Computer Exchange) image file format is associated with PC Paintbrush, an image editing software initially designed for MS-DOS by ZSoft Corporation. At first, PCX files stored a limited range of colors but in time their range was extended to a 24-bit (true color) palette, and PC Paintbrush was adapted for Windows too. Though widely popular during the days of MS-DOS, the PCX format in time lost its appeal and was gradually replaced by formats such as JPEG and PNG.
