The Mesh tab of the Modeling workflow contains tools that let you create or convert contours into meshes for very simple land contours to very complex landscapes with a very lightweight mesh. For example, you can import data containing points, contours, or elements of a landscape and convert it into a mesh. The meshes can be created and merged and manipulated to create a new land structure ready for a building structure.
The Mesh tab of the Modeling workflow contains tools specifically for working with mesh elements, which are surfaces composed of facets that represent a smooth surface. Digital terrain models, for example, are commonly created as mesh elements. The mesh modeling tools let you convert solids and surfaces to mesh elements, create meshes from contours or points, and to modify the mesh elements.
