Layers in Linked and Imported Files
When you import or link a CAD file to a Revit project, you can query, hide, delete, or change the graphic display of layers in the file.
Linking AutoCAD Files to a Project
You can link AutoCAD files to a project to use the drawings as underlays for project views or to place the drawings on sheets to include in the construction documentation set. Any changes to the linked AutoCAD file are displayed in the Revit project.
Using IFC Files
You can use information from Industry Foundation Classes (IFC) files in Revit models.
Importing Images
You can import raster images to a project to use as background images or as visual aids needed during the creation of a model. You can also place imported images on sheets.
Importing Building Components
Manufactured building components that are formatted as Autodesk Exchange (ADSK) files provide design and connection data that you can use to accurately place the component in a Revit project.
Using Point Cloud Files in a Project
Link a Point Cloud file into the project to provide a highly accurate visual reference of the existing condition of a building or site.
Import a Loads Analysis from a gbXML File
When the output from a third-party analysis application is a gbXML file, you can import the file into Revit and use it to design the HVAC system.
