Open almost any CAD file.

Drop a STEP, IGES, STL, OBJ, or GLB. CADDaddy opens it in the browser, keeps navigation smooth, and lets you export or share when you are ready.

Or drop a file anywhere on this page · Guest export included daily

From file to answer in three moves.

CADDaddy keeps the steps obvious and fast so teammates can review without a license, a login wall, or a heavy workstation.

• 01 Upload — Drop a CAD file and start viewing instantly in the browser.
• 02 Inspect — Orbit, confirm STEP millimetres, read bbox L×W×H, measure, and section.
• 03 Export or share — Download a new format or generate a shareable review link.

Built for review, not bloat.

Every tool is tuned for quick inspection, not full CAD authoring. That keeps the experience light, fast, and shareable.

• 01 Big file aware — Handle complex assemblies and large parts while keeping navigation smooth.
• 02 Secure by design — Local processing for supported formats and encrypted transfers for shared files.
