VIEW / 01
Navigate complex models
Orbit, pan and zoom a responsive 3D scene with axes, grid, bounding box, wireframe and orthographic controls.
Private CAD inspection / iPhone · iPad · Mac
CAD beyond the workstation.
Open engineering models on device. Orbit the geometry, verify dimensions, bring supported meshes into the room with camera AR, and leave with a clean inspection report.

The mobile CAD bench / 01
From file to field view.
Open the model, focus on the geometry that matters, and take a supported mesh into the room. CadRoam keeps the workflow compact without hiding technical limits.
INSPECT / 02
Read useful geometry
Review bounds, triangles, surface area and enclosed volume when the source geometry supports those calculations.
PLACE / 03
See scale in camera AR
Place renderable geometry on a detected surface, then fit, rotate and scale it with familiar touch gestures.
A shorter path / 02
Open. Inspect. Share.
No account setup and no cloud-conversion queue. Start from Files, keep a local library, and export a compact inspection PDF with CadRoam Pro.
- 01
Open from Files
Import STL, OBJ or supported STEP geometry from iCloud Drive, local storage or another document provider.
- 02
Inspect on device
Isolate objects, switch display modes and review mesh-derived measurements without uploading the model.
- 03
Place or report
Use camera AR on supported iPhone and iPad, or generate a local PDF for a design conversation.
Field system / 01
The model stays with you.
CadRoam is designed around a local engine. Files are copied only into the private on-device library you control; model contents are never sent to a developer-operated conversion service.
01
Inspect
Orbit, zoom, isolate assembly objects, use wireframe, orthographic and transparency modes, and read geometry metrics when available.
02
Place in AR
Detect a real surface, tap to place, then choose fitted or source-unit scale, pinch and rotate. Camera frames remain in Apple ARKit.
03
Report
Generate an inspection PDF locally and export or share it with system tools on iPhone, iPad and Mac.
Geometry channels / 02
Honest format support.
CadRoam reports exactly what its current engine can render. Meshes work now; advanced curved CAD remains clearly identified instead of silently failing.

MetadataBuilt for real handoffs / 03
A viewer for the space between desks.
CadRoam is useful when the model needs to leave the authoring workstation but should not leave your control.
Engineering review
Carry a reference model into a meeting, isolate parts and discuss geometry without launching the authoring suite.
Workshop checks
Compare overall bounds and part orientation near a bench, machine or assembly area.
3D-print preparation
Review STL and OBJ meshes, triangle density, dimensions and enclosed-volume estimates before handoff.
Client walkthroughs
Use a clean touch viewer or supported AR placement to explain a design away from the workstation.
Private by architecture / 04
Your model is not our dataset.
Model contents are processed on device. CadRoam has no account, advertising, third-party analytics or developer-operated conversion cloud.

- No model-content upload

Straight answers / 05
CAD viewer questions.
Can CadRoam open STEP files?
CadRoam renders faceted STEP geometry and reads useful STEP metadata. General curved B-Rep STEP geometry may not produce a visible mesh in version 1.0, so CadRoam identifies that limitation instead of presenting an empty result as success.
Which 3D file formats render now?
Binary and ASCII STL, indexed OBJ, and faceted STEP geometry render in the current engine. IGES and curved STEP files can be detected and inspected for metadata but may require a future tessellation engine for visible geometry.
Are CAD files uploaded to a server?
No. CadRoam copies imported files into its private on-device library and processes model geometry locally. It does not send model contents to a developer-operated cloud conversion service.
How does augmented reality work?
On a supported iPhone or iPad, CadRoam Pro uses Apple ARKit to detect a surface. You tap to place compatible geometry, then rotate and scale it. Camera access is requested only when you enter AR.
Is CadRoam a certified measurement tool?
No. Mesh-derived bounds, area and volume are inspection aids. Verify source units, tolerances and safety- or manufacturing-critical decisions in the original CAD system or a certified metrology workflow.
