TRIANGULATION, ISOLINES, VOLUME, LOADING of XYZ points files, 3DINTERSECTION, cross sections and a longitudinal profile, color-filled contour map; 7 functions for IntelliCAD versions which can load SDS applications (dll). TRIANGULATION performs the triangulation of a set of 3D points with compulsory interconnections between the points. The outcome is represented by 3DFACE entities. ISOLINES determines the curves of intersection of a set of 3DFACE entities with a set of equidistance planes, horizontally or vertically. The outcome is made up of POLYLINE entities optionally interpolated. VOLUME determines volume and center of gravity of a body limited by 3DMESH and 3DFACE entities. You can load and draw a file of points having the format: Number X Y Z Code. 3DINTERSECTION determines the intersection curves between 2 sets consisting of 3DFACE and 3DMESH entities. The outcome is represented by 3DPOLY entities. You can make the projection over a triangulation of a 2D POLYLINE and generate cross sections and a longitudinal profile corresponding at projection. The POLYLINE may contain arcs. You can also make color-filled contour map. The price is for the first license! You can buy anytime after, other licenses at a lower price!
