3DMap. Constructor

You’ve spent hours trying to align a 3D model of a new building with its real-world GPS coordinates, only to find that every popular map app treats your custom data like a foreign language. The problem isn’t your data—it’s the tool. 3DMap. Constructor by 3D portable inc. is built for the exact moment when a standard navigation app fails: when you need to layer your own 3D objects onto a real map grid, manipulate terrain, and export a navigable environment that isn’t locked inside a proprietary ecosystem.

This is not a viewer; it is a builder. The core mechanics revolve around a precise coordinate-based editor that reads and writes standard GIS and 3D file formats (OBJ, GeoJSON, KML). You drop a point on a satellite base map, assign an elevation, and the app renders that point as a textured volume. The real utility comes from its offline terrain engine—pre-download a region, and the app will construct a polygonal mesh from SRTM elevation data, allowing you to place objects on accurate slopes without an internet connection. The workflow is linear: select a base map layer, import your 3D asset, snap it to a coordinate, adjust pitch and yaw relative to the horizon, then export the entire scene as a single shareable .3dmc file.

Key Advantages

• Native coordinate snapping – Every object you place is locked to a real-world latitude/longitude pair, not a local 2D canvas, ensuring that exported scenes align perfectly with external GPS devices or surveying software.
• Offline mesh generation – The app processes raw elevation data into a textured 3D terrain on your device, allowing you to build and navigate complex environments without cellular service.
• Format-agnostic import/export – Accepts standard OBJ models and exports to KML for Google Earth or GeoJSON for web map integration, eliminating vendor lock-in.
