From Surface

Using this option it is possible to create observation points using a surface as a reference. To create one of these geometries, a NURBS Surface has to be previously selected. This operation is usually done by selecting a previously created surface in the project, or exploding an object to select the desired surface. Then, a new geometry type is added. The number of points in U-Dimension and V-Dimension are parameters for this kind of geometry.
