DWGSee and Autodesk DWG TrueView are both software programs designed for viewing and working with DWG files, but there are some differences between them: To install Autodesk DWG TrueView, you need to download the Autodesk installation program first. Then, using the installation program, you can download the main program package. The package size is around 1.46GB, and the download can be slow. The installation process is complex and usually takes around half an hour to complete. In contrast, the DWGSee installation file package is only about 36.35 MB, making it quick to download and install, usually in just a few seconds.
