It allows you to drag images, zoom in, zoom out, centering, printing.
Advanced printing allows you to print one image to many sheets of paper as "tiles" to glue together afterwards.

Key features:
- Edit/View/Convert AutoCAD DWG/ DXF, HPGL PLT/HGL/PRN/SPL/HG, SVG, CGM, BMP, Tiff and many other file formats.
- Thumbnails
- Measure distance and area with needed scale
- DWG DXF Arcs and Circles can be drawn as smooth curves and saved to EMF as Metafile
- Arcs and Ellipses can be zoomed after pasting to MS Word without quality loss.
- HPGL and HPGL2 Hewlett-Packard formats
- Clip Rectangle for printing and saving to the clipboard and to a file
- Save to clipboard as BMP, EMF (Clip Rectangle supported)
- Save images and drawings to BMP, EMF, JPEG, GIF, DXF format (Clip Rectangle supported)
- Viewing BMP, EMF, WMF, DWG, DXF, HGL, PLT, HG, PLO, JPEG, PCX, ICO, GIF, PSD, TIFF, SVG formats
- Scroll, manual and auto zoom, auto-window size and dragging features allow you to view your images the way you want
- 3D DWG/DXF support
- Structure tab for DWG, DXF, HPGL, SVG, CGM files
- Color and Black-White mode for DWG, DXF, HPGL, SVG, CGM files
- Layers window for DWG and DXF files. You can see the colors of the layers and turn them on/off.
- Printing. 'Tile' feature allows you to print the image onto any quantity of papers with the scale you want. 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 sheet jams (printer problems) you can reprint it
- Mouse wheel scaling like in AutoCAD
- Multi-language support
- Easy and handy user interface.

As a standard set of features new ABViewer offers different tools for manipulating CAD files. Among them we should mention a Rectangle tool, a Redline mode, a Distance tool, a Snap-to-Entities feature. These features were present in the previous version. In the new version they have been significantly improved.
So a Redline mode now allows a user to insert ten types of CAD entities into the currently opened CAD file (there were five types of entities before). New Redline entities are polyline, arbitrary line (pen), dimension, hatch, and arc. All Redline entities can be accessed from the toolbar. A color for each inserted CAD entity can be selected individually in the Properties panel. The remarkable attribute of the Redline mode is that all added CAD entities are saved to the separate file and don't interpose in the current file. It means that the current file is not modified and after closing can be opened in other CAD applications in the regular order. By the user's wish all Redline entities can be displayed, hided or deleted.
By the Distance tool a user can measure a distance between any two points of the CAD image. Just click on the first point and drag the cursor to the second point and you will know the range between two points. While dragging, the direction, vertical and horizontal displacements, and the distance between the first point and the current position of the cursor will be reported in the special rectangle. A new version of ABViewer introduced measuring a distance with a base size. This means that now we can measure an unknown distance on the drawing even if we don"t know the drawing"s scale, taking a known distance as base size
Another nice feature of new ABViewer is Thumbnails mode. Its window is invoked from the toolbar or main menu and allows quick looking through the files of the selected folder. A current folder is easily added to or deleted from Thumbnails folder list by the respective button at the top-right corner. A size of the thumbnail images can be adjusted by two slide bars located at the top of the Thumbnails window.
The newly released ABViewer supports proxy graphics and as its predecessor it also supports Unicode and SHX fonts. The improved user interface is available in 31 languages.
