Mesh From Thickness Values
An offset mesh can be created from a base mesh and a set of thickness values. Thickness data can be imported as values on GIS points, as a 2D grid or as points with values. Once you have this data in the project, right-click on the Meshes folder and select New Mesh > From Thickness Values.
Select the Base mesh and the Thickness values.
To edit a mesh created from thickness values, double-click on it in the project tree.
