Convert SCU to STEP

SCU to STEP for machines that cannot read the original format. Everything runs on your own PC, so a purchased design library never leaves it.

Tired of converting SCU files one at a time? reaConverter processes entire folders to STEP automatically. Handles large batches reliably without crashes or timeouts. No subscription and no per-file cap, however large the library is.

Technical note

How SCU and STEP differ in practice

An SCU file is a job for a blade, so its dimensions are the content. The design was drawn to fit a real object, and a contour that comes out five per cent small looks entirely correct on screen and only fails at the machine, once the material is already spoiled. Measure one known length in the STEP output before cutting from it, and treat the physical size as the thing to verify rather than the shape. A cutter follows outlines and ignores appearance, so fills, stroke colours and line weights in the STEP file have no effect on what the blade does. Two other things do. Every contour has to be closed, because an open path is cut as a line rather than a shape. And duplicated or overlapping contours have to go, because the blade travels each one in turn, cutting the same line twice and tearing thin material.

3D Workflow

From flat drawing to 3D model

reaConverter turns SCU outlines into STEP models by extrusion, so a flat shape becomes a 3D part in one step.

  • Set the extrusion height in millimetres before the run
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs
  • Apply the same height to every file in the batch
