What's a good, lightweight DWG viewer for Windows? [closed]

Solution 1:

Some info from a non-user of CAD:

There is a whole bunch of CAD viewers in here.
The list doesn't include Free eDrawings Viewer.

AcadPVI Shell Extension adds the AutoCAD preview and version to the right-click context menu in Windows Explorer.
AutoCAD Version Explorer (AVE) is a stand-alone program that provides an Explorer-like interface to quickly view AutoCAD preview and version information.

Solution 2:

Irfanview claims to view DWG files, and it's both free and small. It's a very good image viewer but I'll confess to not knowing how well it's DWG support fares, or to what version of DWG it supports.
