CAD Importer DLL is made for developers of the languages which support DLL technology.
Demos for MS Visual Basic, MS Visual C++, Borland Delphi and Borland C++Builder are available.
The DLL exports routines for import extensive DXF, DWG, HPGL, SVG and CGM entities by using the following structure.

News in version 6.1:

• Double precision has been applied.
• AutoCAD™ DWG (all versions including 2008) file format is supported.
• AutoCAD™ PROXY (including AEC) entities are supported.
• HPGL/HPGL2 file format - Bezier splines are supported.
• DXF Loading has been optimized for files with big amount of blocks (layers and styles). In some cases speed is increased up to ten times.
