IFC files, also known as Industry Foundation Classes, are a common format for exchanging 3D modeling data between different software applications. To view IFC files online, you can use web-based 3D modeling software or specialized online viewers. These tools allow you to easily visualize and manipulate IFC files without the need for expensive software licenses or complex installations. By uploading your IFC files to these platforms, you can access and share your 3D models with colleagues and clients from anywhere with an internet connection. This convenient approach to viewing IFC files online enhances collaboration and simplifies the review process for architecture, engineering, and construction projects.
