Lisp surfaces uses an *'Edgesurf'* grid to create a 3d modeling of the Autocad surfaces.
The referential base for the 3d modeling interpolation is a 3d points
database.

The description of the commands that allow the creation of the 3d modeling are:

- Draw an
*'Edgesurf'*grid of autocad whit the settings of x and y axis. - Settings of variously options ralative to: layer, kriging value etc.
- Start the interpolation and draw 3d modeling of the surfaces

Lisp Surfaces uses as interpolation method the "Interpolation between weighted mean
three-dimensional points" formula.

The Lisp Surfaces is able to make about 10.000 grid vertex interpolations in 6 minutes (the drawing of 3d modeling surfaces included).

The Lisp Surfaces options are:

- selection of the layer for the 3D modeling surfaces drawing
- print all points of the 3D modeling grid on the selected layer (DTM - digital terrain model)
- setting of the radius selection value for the interpolation
- setting of the increment value of the selection radius to find the points (at least three) that are required for the interpolation
- setting the limit values for radius selection increment value
- layer report for all points of the 3D modeling grid that requires increment value of the radius selection
- setting of the kriging value for the interpolation

The quality of the interpolation is obviously related to the number of 3D points used for the creation of the 3D modeling grid.

For the setting of the radius selection value you must consider:

- the average distance of the 3D points used for the interpolation
- to choose a small value for the increment value of the radius selection
- to set a limit for the increment value for the radius of selection considering the max value of the radius

The settings of these three options (radius selections and others) will determine the quality of the interpolation vertex grid of the 3d modeling.

Lisp Surfaces uses the Interpolation between weighted mean three-dimensional points formula. With this method of interpolation all points selected (radius selection) are considered for the elevation value of each of the grid vertexes.

If you set a high value for the radius selection obviously the program will find more than the three points needed by the interpolation, but in this case, you will use more points which have a large distance to the vertex of the grid surfaces.

A large distance between the points selected for the interpolation vertex of the grid will give a low quality of the interpolation.
