Form: Import DXF File, Import Information, DXF Import
A DXF file is a file with a .dxf extension containing graphics data saved in the AutoCAD Drawing Exchange Format. This type of file can be read by many graphics programs and is commonly used to exchange data between graphics programs. The DXF file import feature can import model geometry from all versions of AutoCAD up to AutoCAD 2020, and from most other programs capable of writing DXF files.
To import a DXF file into SAP2000, do the following:
Select the File menu > Import > AutoCAD .dxf File command.
The Import DXF File form is displayed.
Navigate to the folder of your choice, select a file, and click the Open button.
The Import Information form is displayed.
Choose the axis corresponding to the Global Up Direction in the DXF file, specify the units the DXF file is written in , and click the OK button.
The DXF Import form is displayed. It features five instances of the list of the layers defined in the DXF file with check boxes next to each of the different layers. Above each list is a label describing the corresponding type of SAP2000 objects to import.
Select the layer or layers on which the AutoCAD objects occur for each type of SAP2000 object to import, and click the OK button.
The following types of DXF objects are imported as the following SAP2000 types of objects:
| 
           DXF Objects  | 
        
           SAP2000 Objects  | 
      
| 
           Points  | 
        
           Special Points  | 
      
| 
           Lines, Polylines, Arcs, Circles  | 
        
           Frames  | 
      
| 
           Points, Lines  | 
        
           NLLinks  | 
      
| 
           3Dfaces  | 
        
           Shells  | 
      
| 
           Polylines, Solids  | 
        
           Solids  | 
      
If you select the same layers to import for both SAP2000 Frames and NLLinks, the AutoCAD lines on that layer will all be imported as frame objects. If you select the same layer for both SAP2000 Frames and Solids, the polylines on that layer will be imported as series of frames objects.
