1. Introduction Terrasolid Spatix is a powerful software module designed for the advanced 3D modeling and vectorization of point cloud data. It operates as an extension within the broader Terrasolid suite, which runs natively on top of Bentley Systems’ MicroStation and OpenCities platforms. While Terrasolid’s flagship products (TerraScan, TerraModeler, TerraPhoto) focus on classification, terrain modeling, and orthophoto generation, Spatix specializes in the precise, semi-automated creation of 3D vector models from dense point clouds—typically acquired via mobile mapping systems (MMS), terrestrial laser scanning (TLS), or UAV-based LiDAR.
