DWGViewX

DWGViewX is an ActiveX component that developers may integrate into their software programs. It allows end users to open and view AutoCAD drawings with the DWG and DXF format, so it's not necessary to install the complex CAD application just for this job.

The tool's packed in a classical-looking interface made from a common window with a plain structure, where you can open DWG and DXF files to view the models.

If there are multiple layouts available, then you can hide any one of them from the design. It's possible to zoom in and out, fit the drawing to the window, pan by mouse, or hide the toolbar.

What's more, you can integrate DWGViewX into the Windows Explorer shell extension to be able to open CAD drawings by opening the file's right-click menu. You can customize font settings, change the background color, as well as print the drawing. There are no other notable options available here.

We haven't encountered any stability problems in our tests, thanks to the fact that the utility didn't freeze, crash or prompt error dialogs. It left a small footprint on system resources consumption, as it needed low CPU and RAM to work properly.

On the other hand, it hasn't been updated for a long time, and its set of features is not that extensive. Nevertheless, DWGViewX provides software developers with a user-friendly CAD viewer for DWG and DXF files.
