RTOPO 2.6  Can now interpolate a set of 3DFACE entities, using quartic triangular patches with G1 continuity!
Is useful in topography for "Digital Terrain Modeling" (DTM) by "Triangulated Irregular Network" (TIN), representation (by 3DPOLY, SPLINE or BLOCK entities) and editing (modify, delete or add) of 3D points, and for triangulation, isolines (contour lines), color-filled contour map, cross sections, longitudinal profile, 2D entities (Line or PLine) projection over a DTM, conversion of a TIN to a regular grid of points and for conversion of existing isolines resulting from maps in points and then in TIN. It exists a modifiable library for codes and BLOCKs. The coordinates, the code and the position (in 3DPOLY or SPLINE) of the points can be modified interactively. The triangulation is performed on a convex hull of a set of points or between an external contour and possibly more interior contours! You can represent the geological stratification resulting from drilling. You can calculate the volume, 3D area and center of gravity of some bodies limited by 3DFACE entities. You can intersect and divide two triangulations (or two sets of 3dmesh and 3dface entities) or a triangulation by a horizontal plane. DXF files can be loaded or saved. RCAD graphic core, distributed together with RTOPO, provides OpenGL real-time orbit, pan, zoom, shading, lighting and motion path animation. RCAD can also run scripts and can be called from other programs. Requirements: Windows 98/XP/Vista/7 (32 or 64 bits) and graphic card with OpenGL hardware acceleration.

TRIANGULATION for AutoCAD 1.4 - TRIANGULATION, ISOLINES, VOLUME, LOADING of XYZ points files, the PROJECTION of a POLYLINE over triangulation, cross SECTIONS and longitudinal PROFILE
An application for AUTOCAD 2002-2012, which makes the triangulation of a set of POINT entities, the intersection curves (isolines) between a set of 3DFACE entities and a set of equidistance plans, horizontally or vertically and calculates the volume and center of gravity of a set of bodies or between surfaces composed of 3DFACE entities. The triangulation is performed on a convex hull of a set of points. You can triangulate million points! The isolines can be interpolated and their colors are according to a drawn legend. The isolines having Z a multiple of a value will be drawn thickened. You can define a clipping parallelepiped for isolines. You can load and draw a file of points having the format: Number X Y Z Code. You can also 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. Requirements: Windows and AUTOCAD version 2002 to 2012.

3DINTERSECTION for AutoCAD 3.9  can convert SOLID to 3DFACE entities!
An application for AUTOCAD 2002-2012, which determines the intersection curves between 2 sets consisting of 3DFACE, 3DSOLID or 3DMESH entities. The outcome is represented by 3DPOLY entities. It can generate 3DFACE entities, perpendicular to a POLYLINE for obtain cross sections and it can draw the conversion to 3DFACE of the 3DSOLID entities. Requirements: AUTOCAD version 2002 to 2012.

DEVELOPED SECTION for AutoCAD 1.3
An application for AUTOCAD 2002-2012, which determines the developed section of one set of 3DSOLID, 3DMESH or 3DFACE entities and vertical planes passing through a 2D POLYLINE which may contain arcs, in XOY plane. Developed section is generated in the vertical plane passing through first segment of POLYLINE, in the current layer. The intersection is generated in the form of 3DPOLY entities. You can set also the "concatenation precision" of the segments of intersection. Requirements: AUTOCAD version 2002 to 2012.

TRIANGULATION for IntelliCAD 3.8 - TRIANGULATION, ISOLINES, VOLUME, LOADING of XYZ points files, 3DINTERSECTION, cross SECTIONS and longitudinal PROFILE; 6 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 the center of gravity of some bodies 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 or 3DMESH entities. The outcome is represented by 3DPOLY entities. You can also 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. Requirements: Bricscad version no longer than 7, Cadopia up to the version 8 (IntelliCAD 2001 up to 6.4), 4M IntelliCad up to the version 11, ProgeCad up to the version 11, Cadian up to the version 2011.

VDAFS TO DXF and NC Converter and Viewer 2.3  
Converts VDAFS file to DXF file (in 3DFACE entities) and generates the NC program for milling a piece composed from 3DFACE entities, by some paths parallel to the machine axis. In VDAFS file will be interpreted the entities of type PSET, FACE (created from the entities of type SURF and CONS) and possibly those of type SURF. 3DFACE entities may result also from 3DFACE or 3DMESH entities from DXF files, from STL ASCII files generates by AutoCAD for solids and from RCAD “3DFace” command. 3DFace entities which describe the surface can be intersected or not perfectly joined! The milling cutter with semispherical head will be always above and tangent to the assembly of 3DFace entities! You can divide the piece into 2 parts through a horizontal separation plane or through a certain separation surface and you can calculate 3D area, volume and center of gravity of some bodies limited by 3DFACE entities. RCAD graphic core, distributed together with VDAFS to DXF and NC, provides OpenGL real-time orbit, pan, zoom, shading, lighting and motion path animation. Requirements: Windows 98/XP/Vista/7 (32 or 64 bits) and graphic card with OpenGL hardware acceleration.

FURNIT 2008 (2.1) - Design of furniture
An application for AutoCAD 2007-2012! You can project bodies composed from rectangular plates or plates defined by POLYLINE or CIRCLE. Technology represented by holes, grooves or edgings, can be applied. On a plate or between 2 plates assemblings can be applied (hinges, pegs, handles, bars, etc.). Furniture bodies can be composed of several plates and assemblings. The plates, the holes, the grooves, the edgings, the assemblings, the bodies and the materials can be modified interactively and archived in order to be reused. Execution drawings for plates and the lists of materials, technology and costs are automatically generated. Requirements: AUTOCAD version 2007 to 2012.
