Draw points in AutoCAD and generate 3D models using data in Excel:
- Create "true" 3D faces with the powerful Delaunay triangulation algorithm, or simply connect all points with a 3D polyline.
- Define point styles and layer colors.
- Apply labels to the points using ID data, coordinates, or both.
- Automatically read text data files which include descriptive lines.

R2V convert raster images to vector by drawing centerlines and outlines. A vector format can be imported to your CAD/CAM or drawing program. R2V supports the Bmp and Jpeg raster format. The output vector files can be saved in DXF, HPGL and TXT format. R2V also converts any True Type font into vector.

TRIANGULATION performs triangulation of a set of 3D points width compulsory interconnections. ISOLINES determines the curves of intersection of a set of 3DFACE entities width a set of plane equidistances horizontally or vertically. VOLUME determines volume and center of gravity of a body limited by 3DMESH and 3DFACE entities. 3DINTERSECTION determines the intersection curves between 2 sets consisting of 3DFACE or 3DMESH entities.

CAD Import .NET is an easy-to-use API for reading AutoCAD DWG and DXF in C#, VB.NET and other .NET applications. It is completely programmed in C# and supports the following entities: 3dFace, Arc, Attdef, Block, BlockRecord, Circle, Dimension, Ellipse, Insert, Layer, Line, LWPolyline, MText, TableItem, Polyline, Solid, Style, Table and Text and properties: Extrusion, LineType, Color, 3D rotation and more. Supports BMP, JPG, Tiff, GIF, ICO.

PowerCAD is a free drawing application which you can easily draw any type of drawing. PowerCad is designed in between CAD and Desktop Publishing style, so you can use the ease of DTP with the power of cad core. You can import/export your drawings.

JFDraw is a pure Java based graphics application and library package.It can help you to complete your mechanical, electronic, architectural graphs drawing applications, or even business process or workflow graphs issues.

PowerCAD technology is developed to provide the application programmers a reusable object library to develop CAD modules for their applications easily. With the PowerCad component you can make a 2D CAD editor with almost no code.With its easy interface, you can handle all drawing needs in your own application including from simplest operation to the most complex one. Your application will be a fully powercad CAD application with scripting.

Vextractor is a vectorizer program for transforming raster images into vector formats by building centerlines and outlines. This tool could be used for the vectorizing of charts, drawings, maps and schemes for input to CAD or GIS systems. You can also vectorize logotypes and other line art images for use in Vector Graphic Design software.
