Designed specifically for the release, this freeware tool allows users to open, browse, measure, and print PCB designs created in Allegro PCB Editor (formerly Allegro PCB Designer). It acts as a read-only viewer, meaning you can inspect every layer, check component placement, verify net connectivity, and perform basic measurements—all without altering the original design data.
