The video introduces SOLIDWORKS 3D Interconnect, which enables seamless collaboration with third-party CAD data without traditional file translation. It allows users to insert or open files from tools like Autodesk Inventor, PTC Creo, and Siemens Solid Edge as if they were native SOLIDWORKS components, maintaining assembly structure and design intent. Changes in the original CAD files are intelligently tracked and updated in SOLIDWORKS, preserving mates and references. Users can also break links for advanced edits or feature recognition. This workflow streamlines design processes, supports mixed environments, and eliminates lengthy import and repair steps, improving efficiency and flexibility in multi-CAD projects.
