In Revit MEP, linking files allows you to reference and utilize models created in other Revit projects or CAD files. Here's an overview of linking files in Revit MEP:br br Types of links:br br 1. Revit links: Link Revit projects (.rvt) to collaborate with other disciplines (e.g., architecture, structure) or to reuse models.br 2. CAD links: Link CAD files (.dwg, .dxf, .dgn) to work with models created in other software or to use as a reference.br br How to link files:br br 1. Link Revit files:br - Go to the Insert tab Link Revit.br - Navigate to the Revit file (.rvt) you want to link.br - Choose the positioning option (e.g., Auto - Origin to Origin).br - Click Open.br 2. Link CAD files:br - Go to the Insert tab Link CAD.br - Navigate to the CAD file (.dwg, .dxf, .dgn) you want to link.br - Choose the import options (e.g., units, scale).br - Click Open.br br Benefits of linking files:br br 1. Collaboration: Link files to work with other disciplines or teams.br 2. Model reuse: Link models to reuse components or designs.br 3. Reference: Link files to use as a reference for your design.br br Best practices:br br 1. Use relative paths: Use relative paths to ensure links are maintained when sharing files.br 2. Manage links: Use the Manage Links tool to manage and update links.br 3.
