AutoLISP source code can be run on AutoCAD or IntelliCAD (Bricscad, ProgeCAD, Cadopia, etc). They can be modified, included in programs that you sell, and can be run on any number of computers. There are programs for:
- "Triangulation" will generate triangular 3DFACE entities, on the convex hull of the set of points,
- "Load XYZ and 4D files"; file types: x y z color, x y z scalar, x y z r g b, no. x y z code,
- "B-spline control polygon and interpolated contour lines" creates the control polygon and interpolates a POLYLINE with cubic B-Spline; the interpolated curve passes through the initial points and you can control its curvature; you can also generate interpolated contour lines,
- "Intersect 2 3DFACE and contour lines" intersects 2 triangular 3DFACE entities and generatea the contour lines,
- "Modify longitudinal profile" contains 3 new commands which increase productivity in the modification of drawings
YTE changes the Y texts of some points, relative to an origin point,
XTE changes the X text of some points, relative to X=0,
PTE inserts elevation and slope with triangle on a POLYLINE,
- "DWG to XYZ" converts a DWG file to an XYZ file of points,
- "Longitudinal profile and cross sections" for the projection over a triangulation of a 2D POLYLINE, useful for surveyors and designers,
- "Cut and fill volume" calculates the filling and digging volumes between the project and the land surfaces; the surfaces must be 3DFACE or 3DMESH entities, having different colors between project and land,
- "Surface Flatness", useful in analyzing the flatness of a point cloud, which must be triangulated beforehand,
- Custom "Hatch styles from a DWG",
- Get polyline vertices.
You can test these programs in the programs in which they were implemented:
- RTOPO Hydrology CAD for topography,
- Topography in AutoCAD or BricsCAD,
- 3DINTERSECTION for AutoCAD or BricsCAD,
- Cut and fill volume in AutoCAD or BricsCAD.
