Technical note

Before you convert SCU to STL

A 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 STL output before cutting from it, and treat the physical size as the thing to verify rather than the shape. Cutting projects give each object a role: cut, score, draw or perforate. STL carries that separation as layers, or as groups and stroke colours, depending on the format. Confirm it survived before running the job, because a file where everything landed together will be processed in one pass with one tool, and score lines will be cut straight through.
