The interface looks familiar, so users shouldn't experience any navigation issues. Opening a drawing can be done using the file browser only, since the drag-and-drop feature is not supported.
Standard tools include print, zoom, pan across drawing area, rotate, and select (predefined 3D view).

As far as preferences are concerned, you can specify the initial viewing mode for DXF and DWG files (e.g. zoom drawing to fit, last saved) and raster (e.g. initial rotation for BMP and JPG).

In addition, you can establish the printer initial page orientation, raster images in drawings options (e.g. ignore always), and Xrefs in drawings (e.g. browse if not found), as well as enable confirmation on quit and hide menus from the main application window.

Administrators also have the possibility to manage user permissions when it comes to printing, saving and copying to the Clpboard, and markups (whether they can be embedded into DXF and DWG drawings or not).

Other options of CAD Viewer focus on a search function, export to PDF format and email, drawing recovery for viewing, text touch-up options (e.g. edit, move, copy, delete), image mode (e.g. fast draw, smooth), layer manager, black and white filter, and more.

CAD Viewer is very responsive to commands and runs on a pretty low amount of CPU and RAM, so it doesn't put a strain on overall performance or interfere with the runtime of other applications. We have not come across any issues in our tests, since the app did not hang or crash. In conclusion, CAD Viewer offers a simple alternative to viewing CAD files.
