Mob3DMod - 3d model viewer

The perfect mobile tool for engineers, designers, manufacturing professionals, and anyone who works daily with 3D models.

Precise Measurements & In-Depth 3D Model Analysis on real B-Rep geometry

Point-to-point & minimum distances, angles, radii/diameters, edge lengths, perimeters, surface areas, volumes, mass (with density), center of mass, curvature, moments of inertia, draft angles, minimum wall thickness, hole detection — all with true engineering accuracy for professional analysis of 3D models.

Broad CAD Format Support for Viewing 3D Models

STEP • IGES • BREP • STL • OBJ • glTF / GLB • PLY • VRML • XBF + more

Open any 3D model from files, email, cloud storage — the app auto-detects the format and loads your 3D model instantly.

Powerful Interactive 3D Viewport for 3D Model Viewing

• Smooth orbit (trackball), pan, zoom with inertia

• Standard views + isometric

• Perspective / orthographic projection toggle

• View Cube, Zoom to Fit / Zoom to Selection

• Walk-through mode for large-scale 3D models and assemblies

Full Assembly Navigation & 3D Model Analysis

XDE-based assembly tree:

• Expand / collapse / search / filter by name

• Select → highlight in 3D viewport

• Toggle visibility, adjust transparency, change part colors

• Rich metadata for every 3D model: volume, surface area, center of mass, bounding box, triangle count, material, layer, custom attributes

3D Model Converter & Export Features

Export your 3D model to STEP, STL, OBJ, glTF/GLB, PLY + high-res screenshots — perfect for 3D printing, sharing with colleagues, or further editing.

Built with Flutter + Open Cascade Technology: desktop-grade precision, excellent performance, and a modern, touch-friendly interface for 3D model viewing, 3D model analysis, and 3D model conversion anywhere you go.

For professionals who need a serious tool in their pocket — not just a basic viewer.
