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.
