Load XYZ and 4D files AutoLisp source

It can load and draw XYZ and 4D point files. The following file types are allowed: x y z color, x y z scalar, x y z r g b, no. x y z code.
In the case of “x y z scalar”, the points will be drawn with colors, according to a legend of 20 colors, depending on the value of the “scalar” field.
In the case of “no. x y z code” you can opt for drawing around the point the number, the code and the Z elevation. You can also indicate the step on X and Y of an axis grid.
You can also use a command which will export from the current DWG, a point file of the form “x y z color”.
AutoLISP source code can be run on AutoCAD or IntelliCAD (Bricscad, ProgeCAD, Cadopia, etc.) on any number of computers, without any restrictions.
