*SAP2000* models may be *exported to DWG* (Drawing) format through the process which follows:

\\

# Within [SAP2000|sap2000:home], select File > Export > AutoCAD .dxf File, as shown in Figure 1:
\\
\\
\\  !Figure 1.png|align=center,border=0!\\
{center-text}Figure 1 - Export SAP2000 model to DWG format{center-text}
\\
\\
# Select AutoCAD .DWG Files (*.DWG) from the drop-down menu within the browse window, as shown in Figure 2:
\\
\\
\\  !Figure 2.png|align=center,border=0!\\
{center-text}Figure 2 - Select file for export{center-text}
\\
\\
# Choose the SAP2000 model you wish to [export|kb:Export] to DWG format from the list of saved files which are available.
\\
\\
# Select Save to begin the conversion process. During conversion, the destination software will automatically open and then close. The SAP2000 model will then be available in DWG format.

\\

A few notes which concern this process are as follows:

* AutoCAD or another DWG-supported software must be installed on the desktop to successfully export a SAP2000 model into DWG format. DXF [import|kb:Import] and export, however, does not require AutoCAD installation on the desktop.

* SAP2000 uses {new-tab-link:http://en.wikipedia.org/wiki/ActiveX}ActiveX{new-tab-link} late binding to create AutoCAD entities.

* SAP2000 objects will convert into DWG entities as described in the following table:

\\

|| || MAPPING content || ||
|| || SAP2000 object || DWG entity ||
| 1 | [Point|kb:Joint] | AcadPoint |
| 2 | [Line|kb:Frame] | AcadLine |
| 3 | [NLink|kb:Link] (2 or 3 points) | AcadLine |
| 4 | NLink (1 point) | AcadPoint |
| 5 | [Area|kb:Shell] | Acad3DFace |
| 6 | [Solid|kb:Solid] | AcadPolyFaceMesh |

*NOTE:* DWG Solid objects differ between import and export. For import, AcadDb3DSolid is useful for DWG files. For export, AcadPolyMesh is useful for obtaining object coordinates.
