Working with drawing fragments:
The ability to copy parts of the drawing to the clipboard in both raster (BMP) and vector (EMF) format.
The selected area can be printed separately from the rest of the drawing.
The selected area can be saved to a separate file (DXF, PDF, BMP and other formats).
Editing Drawings:
ABViewer allows you to edit not only standard CAD formats such as DWG and DXF, but also vector files: PLT, SVG, CGM. The program contains all the tools of a professional editor, which makes it possible to work in ABViewer as well as in "heavy" editors, such as AutoCAD or Compass.
Conversion possibilities:
Copying data in BMP, EMF/WMF format to the clipboard.
Export drawings to raster formats BMP, JPEG, GIF, TIFF with convenient settings.
Saving vector data when exporting to PDF, DXF, PLT, SVG, CGM, SWF, WMF, EMF formats.
! Important: When using the Cropping Rectangle tool, the conversion will be performed only for the corresponding part of the drawing.
Batch conversion and printing:
If you have a lot of files that need to be converted to another format or printed, then you don't have to spend a lot of time on it. ABViewer has the ability to simultaneously convert and print in batch mode - using the same settings for all files.
Fast loading and scaling of large black and white raster files:
ABViewer uses know-how to work with 1-bit (black and white) raster formats. Huge files with sizes of 20 by 15 thousand pixels are loaded in less than a second and are scaled almost instantly, which is very convenient when working with scanned drawings in TIFF format.
Sizing tools:
The ability to quickly visually adjust the scale factor for taking measurements – no more additional calculations on the calculator!
Changing lengths, areas and perimeters.
Working with CAD files:
You can hide all sizes or texts with a single mouse click
Easy switching between files
Binding to objects has a large number of settings and works not only when editing drawings, but also when using "rulers"
Measuring distances in the drawing, including setting the scale factor.
Viewing and editing in 3D mode
Viewing in six orthogonal projections and four isometric views.
Automatic rotation of the uploaded CAD file by a specified angle.
Working with layers
Color and black-and-white modes for CAD files
Setting the background color
DWG/DXF/SVG/CGM Arcs and Circles can be drawn as smooth curves and stored in EMF as Arcs and Ellipses of Metafiles, which makes it possible to scale them without loss of quality
Setting the number of line segments when drawing a circle, arc, ellipse, and spline
Combining drawings into a single file.
The ability to view the structure of CAD files.
Support for SHX fonts, including UNICODE and BIGFONTS.
File Search:
The Bookmarks and Explorer panels provide quick file navigation. The "Thumbnails" subroutine makes it possible to view all files in the directory before opening them, including viewing DXF, PLT and other files that are not shown by Windows or ordinary viewers. You can navigate through the files opened in ABViewer very quickly thanks to the modern organization of documents in tabs.
File Navigation:
Dynamic scaling of the drawing using the mouse wheel, similar to AutoCAD, Text search functions and dots will quickly move you to the desired part of the drawing. If you only need the outline of the part in the drawing, then you can remove all texts or dimensions by pressing one key – now you do not need to open layers and change visibility for this operation.
