Advanced surface creation

The Topoplan Module creates surfaces by several methods:

  • Create TINs by points
  • Explode clouds into points
  • Import elevation grids
  • Convert models to 3D faces, submeshes, and polyface meshes

Textures applied to meshes and calculations performed

The Topoplan Module applies textures on surfaces:

  • Flat Texture Overlay applies textures to surfaces from point clouds
  • Raster texture mapping applies raster images as textures on surfaces
  • Mesh coloring by height colors surfaces according to their elevation
  • Calculating volumes between models calculates volumes of surfaces - total, difference, and balanced for excavation works
  • Calculating surface volume calculates volumes of surfaces and surface areas
  • Calculating area defines the areas of surface patches

Multiple data sources for creating digital terrain models

The Topoplan Module creates digital terrain models from multiple data sources:

  • Importing points from text files
  • DEM imports
  • Unloading points from previously imported point clouds
