Simply upload your DWG file to the AutoCAD Web App, and you can begin accessing and editing your design data immediately. This is a convenient option for those who only occasionally need to work with DWG files.

Another online tool for opening DWG files is DWG FastView. This lightweight and fast web-based application allows you to open and view DWG files without needing to install any software. With DWG FastView, you can quickly review and annotate DWG files from any device with an internet connection.

These online viewers allow you to access and review DWG files from anywhere, making collaboration on design projects seamless.

In conclusion, opening and viewing DWG files online is easily achievable with the right tools.
