GC‑Prevue is a Windows-based Gerber data viewer developed by GraphiCode for use in the printed circuit board (PCB) supply chain. It is designed to open, inspect, measure, and document electronic manufacturing output files generated by CAD systems. The software reads common electronic manufacturing formats including Gerber, AutoCAD DXF and DWG, Barco DPF, Excellon, Sieb and Meyer, HPGL, and HPGL2. It is used by PCB designers, fabricators, and assemblers to verify manufacturing data before production. GC‑Prevue supports verification of design data, measurement of features, preparation of print documentation, quoting activities, and revision management. It provides visual inspection tools and dimensioning functionality to analyze board layers and geometry. The product is distributed as a 12‑month single‑user license, installable on a single PC per purchased license, and includes technical support for the subscription period. It is positioned as a standard Gerber viewer within the PCB manufacturing workflow.
