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.

Workflow
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.
Upload
Drop a CAD file and start viewing instantly in the browser.
Inspect
Orbit, measure, section, and confirm geometry in seconds.
Export or share
Download a new format or generate a shareable review link.
Capabilities
Built for review, not bloat.
Every tool is tuned for quick inspection, not full CAD authoring. That keeps the experience light, fast, and shareable.
Fast import
Open STEP, IGES, STL, OBJ, FBX, GLTF, and more without installing anything.
Precision tools
Measure distances, inspect cross-sections, and review assemblies with clarity.
Export ready
Convert to STL or GLB and keep downstream teams moving.
Shareable reviews
Send a review link so stakeholders can approve without accounts.
Secure by design
Local processing for supported formats and encrypted transfers for shared files.
Big file aware
Handle complex assemblies and large parts while keeping navigation smooth.
Formats
The formats your team already ships.
