Welcome to ComputationalCAD

ComputationalCAD for AutoCAD is an easy to use, top-performing and robust computational geometry add-on for AutoCAD. Due to its advanced algorithms, ComputationalCAD for AutoCAD is perfectly suitable for large scale computations and Digital Terrain Modeling (DTM).

ComputationalCAD for AutoCAD focuses on efficiently processing the geometric primitives point, line / polyline and 3dface in AutoCAD. Methods comprise conforming Delaunay triangulations, 2d and 3d convex hulls, minimum enclosing rectangles and circles and 3d bounding boxes. In combination with ComputationalCADs point-on-solid generation tool, this allows to container load 3d solids.

ComputationalCAD for AutoCAD reconstructs surfaces from unordered triangular or quadrilateral wireframe data.

ComputationalCAD for AutoCAD allows generating meshes from surfaces consisting of unordered faces, to convert such surfaces into a solid, to compute the silhouette of such surfaces and to colorize them.

ComputationalCAD for AutoCAD also provides a couple of useful tools, including point-on-entity generation, fast polyline generation from unordered lines, polyline simplification, contour line computation, surface interpolation / projection and face slicing.

ComputationalCAD for AutoCAD supports several simple but powerful plain ASCII import and export formats, including Microsoft Excel csv, xml and stereolithography STL. This enables a workflow of pre- and post-processing geometric primitives outside AutoCAD and then using ComputationalCAD for AutoCAD to run high-level methods within AutoCAD.
