Design Review

Leave feedback on the drawing and review it with your team and partners

Add comments where you need them with a single click, manage review history, and capture the screen to share instantly. Designers, CAM, and DFM reviewers finalize fabrication data on the same screen before mass production, and markups and snapshots carry straight into work instructions and review documents.

Layer View

Toggle layers on and off to check everything at a glance

Freely turn copper, solder mask, silkscreen, and drill layers on or off or overlay them to check whether drills align over pads and whether any layer is missing before release. Compare multiple sets of fabrication data in one view to verify that the design intent matches the released data.

Measure

Measure clearance, trace width, and drill dimensions precisely

Measure trace spacing, line width, pad and aperture sizes, and drill diameters in a few clicks. Verify that annular rings and clearances meet manufacturing standards before release, so you can catch DFM and DRC risks before handing data to the manufacturer.

Highlight

Highlight the traces or areas you want for fast navigation

Highlight specific traces, apertures, or areas in color to follow patterns and shapes intuitively within complex data. Narrow the review scope to just the part you are checking and quickly find where to leave comments.
