Key Capabilities
01
Multi‑format viewing
Supports .glb, .gltf, .fbx, .stl, .obj, .ply, .3mf, .dae, .3ds, .dxf, .step, .iges and more, viewable directly in the browser or native apps.
02
Offline privacy
All files are processed locally; no data is uploaded to a server, enabling use without an internet connection.
03
Measurement tools
Measure real‑world distances by clicking two points, with units like mm, cm, and inches.
04
Render modes
Switch between solid, wireframe, and X‑ray visualizations with a single keystroke.
05
Cross‑section slicing
Drag a plane through the model to reveal interior geometry, useful for checking wall thickness and hidden features.
06
HDRI lighting environments
Apply studio, sunset, overcast, or night HDRI lighting to preview material appearance under realistic illumination.
07
Real‑scale grid
Display a grid calibrated to real‑world units for accurate sizing.
08
Print‑readiness checks
Detect non‑manifold geometry, flipped normals, and minimum wall thickness to ensure models are ready for 3D printing.
09
Capture export
Export a screenshot as PNG or an animated GIF of the model rotating.
10
Mobile AR support
iOS and Android apps provide file associations, offline access, and augmented‑reality viewing via Quick Look on iPhone/iPad.
Use Cases
