CADViewX is an AcitiveX library for viewing and printing AutoCAD DWG & DXF, HPGL, SVG and CGM files. The library also supports BMP, JPEG, windows metafile and GIF images. Powerful print, easy mouse wheel zoom and right-mouse-button padding are convenient features. The Print system is the same as in ABViewer software. The 'Tile' feature allows you to print the image onto any number of papers with any desired scale. Predefined sizes for standard formats (US: A, B, C, D, E; ISO-A, DIN: A4, A3, A2, A1, A0). Any 'tile' can be printed independently of other 'tiles', so if one page fails (e.g. printer problems) you can reprint just that page.
The library has demos for VB, VB.NET, C# and HTML. Read more.
