Type and calculation of the number of points on a topographic surface

The "Type" column has been added to the project's table of topographic surfaces, available in the application's toolbar. In this new field, users can indicate whether the surface has either a "Mesh" or a "Grid" type definition. A "Grid" type topographic surface is defined by points arranged on the basis of a grid, whereas a "Mesh" type topographic surface is composed of vertices that are arranged without an organised structure. "Grid" type surfaces are more efficient when represented on the drawing area of the program, as the triangulation process has a lower computational cost. However, the points that make up this type of surface cannot be added or edited from Open BIM Site.

Along with the type of the topographic surface, the number of points that define it is also displayed.
