DWG, DXF & 3D CAD Viewer

Open three DWG, DXF, STEP, IGES, STL or OBJ files free. Unlock unlimited local viewing, camera AR and PDF reports once—no subscription.

Open DWG and DXF drawings or STEP, IGES, STL and OBJ models. Inspect your CAD files and measurements on your device.

OPEN AND INSPECT

• Import drawings and 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 Drawing and model geometry is processed locally. CadRoam does not upload file 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.
