AutoCAD Web: Your Reliable Tool for Viewing and Marking Up DWG Files

In today’s fast-moving and digitally driven environment, professionals across industries need tools that deliver flexibility, ease of use, and efficiency. Whether you’re an architect, engineer, product designer, CAD expert, or even a hobbyist, being able to access and edit DWG files on the go can be a major time-saver. That’s where AutoCAD Web shines — it’s a powerful solution for viewing DWG files, with lightweight markup and editing tools that enhance collaboration and simplify design changes from anywhere. In this blog post, we’ll walk you through how to view and mark-up 2D and 3D DWG files using AutoCAD Web, along with other key advantages it offers.

About DWG Files

Introduced by Autodesk in 1982 alongside the first release of AutoCAD, the DWG file format has since become a cornerstone in the design industry. As AutoCAD’s native file type, DWG files store detailed 2D and 3D geometry, annotations, and metadata, making them essential for thorough design documentation. Their widespread use across various industries supports seamless collaboration and ensures compatibility between professionals. Known for their accuracy and durability, DWG files are also ideal for long-term storage and reliable design workflows—making them a critical tool for creating, sharing, and preserving complex CAD drawings.

TrustedDWG and Enhancing File Security

TrustedDWG is an Autodesk-developed technology designed to protect the accuracy and compatibility of DWG files. It confirms that a file was created or edited using Autodesk software or approved tools, ensuring no data has been lost or compromised. With TrustedDWG, AutoCAD Web helps users maintain reliable, high-quality files that meet professional standards for design and documentation. This feature plays a vital role in preserving data integrity and ensuring smooth interoperability across different Autodesk software versions.
