## What is STEP, IGES & 3D CAD Viewer?

Open engineering models where the work happens. CadRoam is a private 3D CAD viewer for iPhone, iPad and Mac, built for fast model review away from the workstation.

OPEN AND INSPECT
- Import models directly from Files
- Orbit, pan and zoom a responsive 3D scene
- Browse, hide and isolate objects in multi-part models
- Review bounds, triangle count, surface area and enclosed volume when available
- Switch wireframe, transparency, axes, grid, bounding box and orthographic views

PRIVATE BY DESIGN
Model geometry is processed locally. CadRoam does not upload model contents to a developer-operated conversion service, requires no account and includes no third-party advertising, analytics or tracking SDK.

CAMERA AR AND REPORTS
On supported iPhone and iPad devices, CadRoam Pro places compatible geometry on detected surfaces with Apple ARKit. Choose fitted scale or source units, then move, rotate and resize the model. Generate a compact inspection PDF locally and share it with system tools.

Open and inspect three unique CAD files free. Reopening the same file or using the built-in sample does not consume another free opening. A one-time CadRoam Pro Lifetime purchase unlocks unlimited private opening, camera AR and PDF report export across iPhone, iPad and Mac. No subscription.

CURRENT FORMAT SUPPORT
- Binary and ASCII STL
- Indexed OBJ with objects and groups
- Faceted, AP242 tessellated and exact B-Rep STEP
- IGES B-Rep and curved surfaces

STEP and IGES coverage varies across schema editions and exporter-specific records. CadRoam is not a certified metrology system.
