5.3. Create Mesh from Surface
This tool allows us to create a mesh file from a surface.
By clicking the Surface button, one can choose a surface other than the current drawing. In File type, one has to specify the type of mesh to be created: either ASCII Mesh or Binary Mesh. When one or other option is selected, the approximate size of the file to be created is displayed.
The possibility of specifying a Boundary exists by designating a closed polyline with the Select button. In this way, the mesh would then be defined only within the boundary polyline. This check makes the mesh creation process slower, and it is therefore not advisable for very dense meshes.
The option Extrapolate cells in perimeter is used to obtain meshes with a larger surface.
Lastly, the Cell Size parameter determines the separation between mesh coordinates. The smaller this value is, the denser the mesh, and the file will occupy more space. However, if the mesh is used to calculate volumes, the result will be more accurate. See volume calculation by Mesh Difference in the Volumes section.
This command ends with the creation of the relevant file. To view the results, use the Maps > Draw Mesh command.
