## What is STL Viewer?

Open your STL file and review the 3D model on iPhone or iPad. STL Viewer brings together model viewing, geometry inspection and technical documentation for 3D printing, prototyping and engineering workflows.

FROM FILE TO MODEL
• Open binary or ASCII STL files.
• Rotate, pan and zoom with multitouch gestures.
• Explore technical views and rendering modes.
• Review model details away from your workstation.

INSPECT WITH PRO
Inspect mesh health, open edges, degenerate faces and geometry. Use surface measurements, dimensions, area, volume and section planes. Assign your file's unit: the STL format does not store units.

DOCUMENT WITH STUDIO
Studio adds technical PDF reports with project information and geometry and mesh summaries, generated on your device.

LOCAL PROCESSING
Model geometry is processed on your device and is not uploaded to our servers. Practical file limits depend on your device's memory and capabilities.

This is a paid app download. Advanced inspection and measurement require Pro; PDF reports require Studio. Subscription features and prices are shown before purchase and can be managed in your Apple account settings. This version's interface is in English.
