Gerber viewer

The tool loads Gerber RS-274-X and Excellon drill data, parses layer content, and renders a multi-layer preview. It detects units (mm or inches) and origin, and it associates each copper, mask, or silkscreen layer with a distinct color to aid inspection. The uploaded files are validated for consistency and completeness before rendering.
The core engine converts Gerber commands into vector shapes, computes the board extents, and overlays drill data on the same canvas. It highlights mismatches such as missing copper layers, unexpected pad sizes, or misaligned drills, enabling quick triage of fabrication risks.
Users benefit from go/no-go data readiness with a single consolidated view, which reduces rework in manufacturing, supports panelization checks, and speeds handoffs to fabrication partners.
Key features include layer color coding, per-layer visibility, unit-aware scaling, and optional export of composite previews and data reports for archival and quality control.
