*SAP2000* models may be *exported to* {new-tab-link:http://en.wikipedia.org/wiki/Autocad}AutoCAD{new-tab-link} 2012 as {new-tab-link:http://en.wikipedia.org/wiki/Dxf}Drawing Exchange Format{new-tab-link} (*DXF*) files using the procedure which follows:

\\

# Save the [SAP2000|sap2000:home] SDB file within the C:\Program Files\Computers and Structures\SAP2000 folder. This is where models must be saved to perform SAP2000 operations.
\\
\\
The example model we will use for this demonstration contains at least one [joint|kb:Joint], nonlinearone-joint [link|kb:Link], two-joint link, [frame|kb:Frame], [shell|kb:Shell], and [solid|kb:Solid] object, as shown in Figure 1:

\\
\\
# Verify that AutoCAD .DXF Files (*.DXF) is selected from the 'Save as type' scroll-down menu, then save the model as a DXF file outside of the C:\Program Files\Computers and Structures\SAP2000 folder (Figure 3). Files within this folder may only be accessed through SAP2000.
\\
\\
{info}
*Note:* AutoCAD does not need to be installed on the desktop to save in DXF format. [Import|kb:Import] and [export|kb:Export] between SAP2000 and DXF format does not require AutoCAD installation because DXF is a text file of published and publicly available format.

# Go back to the C:\Program Files\Computers and Structures\SAP2000 folder, then double-click SAPDXF (Figure 5). This is the DXF layer template which will transfer SAP2000 objects into AutoCAD layers.

# For each [SAP2000|sap2000:home] object type listed under Assign Layers, two options are available for transfer into DXF layer type, described as follows:
\\
\\
#* *Default layer assignment*. Coordinate SAP2000 object types with the DXF layer types available under each scroll-down menu to the right. Note that each menu has another scroll bar which presents additional options.
\\
\\
#* *Manual layer assignment*. For each DXF layer name desired, type the name into the lowest box, then select Add Layer. These options will then become available within each scroll-down menu, as demonstrated with Layer 3, shown in Figure 6:

# Select OK once layer names are assigned to each object type which occurs within the SAP2000 model which will be [exported|kb:Export] to AutoCAD. The model will then be saved and available as a DXF file located in the previously specified folder, as shown in Figure 7:

*NOTE:* The model will initially open with an enlarged Top view in 2D. Select a corner of the ViewCube and then use the View > Orbit feature to adjust the 3D view and review the imported model.

h2. How are text labels for section sizes exported from SAP2000 to DXF?

*Answer:* Text is exported to DXF only when active-window views are 2D. All labels visible in active windows will be exported.
