How to Edit and Verify Gerber Files Using GC-PrevuePlus Before a printed circuit board (PCB) enters production, engineers must ensure the manufacturing files are entirely error-free. While standard viewers allow you to check your work, GraphiCode’s GC-PrevuePlus upgrades this process by offering production-ready design verification, Gerber editing tools, and multi-format translation within a single tool.
Making edits directly to your manufacturing data allows you to fix urgent layout issues or format incompatibilities immediately without going back through your native CAD environment. 1. Importing and Setting Up the PCB Data Package
To verify or modify a design, you must first build a clean graphical database from your raw fabrication files.
Launch the Import Wizard: Navigate to File > Import to load your Gerber (RS-274X or standard Gerber) and Excellon drill files.
Set Directory Locations: Go to the Locations tab via Tools > Customize > File to keep your import paths organized.
Define Unit Systems: Match the unit scaling (Metric or Imperial) and decimal resolution used in your CAD export to prevent rounding alignment errors.
Verify Stackup Orientation: Check that no copper or silkscreen layers are unintentionally mirrored; every layer should look top-down straight through the board. 2. Navigating and Managing Layers
