![]() ![]() Colors: Preserve (if you want to preserve the colors of the layers in CAD file).If you do not check this box, the CAD file will appear in all views, including 3D views. Check the “Current View Only” checkbox if you want this CAD file to be visible only in the view it is being imported (Ground Level Floor Plan).A Link CAD Formats dialog box will appear.Go to Insert tab -> Link -> Link CAD (If you would like to import a CAD file not link it, you may chose to go to Insert tab->Import-> Import CAD).Navigate to the floor plan of “00 Ground Level”.This project file already contains model geometry for basement floor, grids, levels and section views. Open the tutorial file ‘TutorialImportCAD_Input_LearningRevitOnline.rvt’ in Revit.Just in case, if you need to get back to the original version. Copy the original file before modifying for import.If you do not need them, unload/remove them. If you need Xrefs, then bind them in your drawing.Check if drawing units and file units are consistent.If necessary, copy the geometry you would like to import and paste it into a new CAD file, to avoid any unnecessary references. For example, if you are importing a layout drawing of a particular floor, try to have only that layout in the CAD file. Do not crowd multiple drawings in one CAD file while importing in Revit. Many CAD users like to put layouts, elevations, sections, etc all in one CAD file.You may also choose to Freeze the layers which are not required. Have only those geometries/layers in the CAD file which are necessary for you to use in Revit (this will reduce the file size and the memory required in Revit).Open your CAD program and make sure you have done the following: Make sure that you have the CAD file “Ground Floor Layout_For Import.dwg” and have prepared it as per the tips in step 2.“TutorialImportCAD_Input_LearningRevitOnline.rvt”.If you do not have the following files, please download them from here. Link a CAD file containing the Ground floor layout of the sample project into Revit and place it on the “00 Ground Level” Floor Plan as shown below.Controlling the visibility of the CAD file.Importing a CAD file will increase the size of the Revit project file, but in turn will use less memory. However, if you do not expect the CAD file to change, it is best to Import it. If the CAD file is revised, then you can simply reload the linked files in Revit and see those changes. If you expect the CAD file to change, it is best to link it. You can either import a CAD file or you can link it. If you already have some details drafted in CAD, you may import them in Drafting view and use them in Revit. Another popular reason to import CAD files into Revit is to use them for detailing purposes. REVIT model geometry is then built by tracing over elements in CAD file. CAD drawings are then imported/linked in Revit to be used as references/underlay. ![]() Some architects like to begin their design in CAD software tools. ![]()
