Architects, contractors and consultants all need tools able to handle the terrain as it actually is – in three dimensions – for planning, volumetric calculation, visualisation and documentation purposes. This document describes how Powel 3D Terrain meets these challenges. The program supports the entire process from the import of maps and terrain data to the production of stake-out data, drawings and zoning plans, as well as the calculation of mass volumes as a basis for tendering.  Naturally, it is also possible to work with several alternative solutions in parallel.
