STL Viewer - 3D Mesh

Measure, slice, inspect STL

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Open complex STL files, inspect every edge, and share clean results. STL Viewer is a fast native 3D viewer for makers, engineers, print shops and CAD reviewers who need to inspect STL files on mobile. Open binary or ASCII STL files from local storage, email attachments, cloud drives or file managers. The model is copied into a private local library so it can be reopened without accounts or cloud upload. Inspect complex models with shaded, wireframe, point, normal-vector, printability and wall-thickness views. Switch standard directions, fit the model, zoom in on details and keep the boundary and dimension overlays under control. Measure point-to-point distances, angles and X/Y/Z bounds. Use cross-section slicing, volume and surface-area analysis, component coloring and printability checks to catch scale and mesh issues before sharing or printing. Keep STL inspection local without accounts or STL cloud upload.
