What functionality does the 'Import CAD' option in Revit provide?

The 'Import CAD' option in Revit is specifically designed to bring in CAD drawings into a Revit project, which can be extremely useful for layering design elements. This functionality allows users to reference existing CAD files as background drawings, making it easier to align and place Revit elements in relation to the imported geometry.

The process enables architects and designers to leverage previous work or external documentation, enhancing productivity by not having to recreate existing designs from scratch. This is particularly valuable for projects involving renovation or when integrating new designs with existing conditions.

While Revit does have other methods for exporting and converting files, the primary function of 'Import CAD' is centered on the ability to incorporate CAD drawings into the Revit environment, serving as a framework for further design development.
