By CADSoftTools.

Shareware 25 Jun 2017


CAD .NET is a library that allows specialists to develop in .NET environment (C#, VB.NET, J#) software to work with CAD files. Its basic features include creating, importing and exporting of CAD formats (AutoCAD DWG, DXF, HPGL, PLT, etc), raster images (BMP, JPG, TIFF, GIF, etc) and metafiles (EMF, WMF), their visualization and printing. A developer can get access to drawing data, the structure of which is presented in accordance with the format specification, and access to additional entity data. For example, it is possible to get points that form the curve for splines and polylines. G-code generation from DWG and DXF formats for CNC machines is also available. This library can be applied for different purposes including work with industrial drawings, databases, document management systems, CNC machining, monitoring and remote control programs. CAD .NET may also be used in server applications on the basis of the ASP .NET technology. CAD .NET provides the control elements to display CAD drawings. The use of ready-made controls makes the process of developing simpler in case you need drawing visualization. An important feature of CAD .NET is that it does not require AutoCAD or other third-party applications installation. The library assembly is compiled with the ANY_CPU directive which makes it compatible with x86 and x64 platforms. The compilable library version is delivered with illustrative demo projects and detailed documentation. Also on our website you can find the brief descriptions of the most important classes that will be useful in the beginning of work with CAD .NET. The high quality of library, prompt free support and royalty-free licenses make CAD .NET an excellent variant for implementation. With the help of CAD .NET work with CAD files will be much easier and efficient.
