To use SwitchBack with AutoCAD
1 For AutoCAD (version 2004 or later) or products based on it, first open the product in the usual manner,
and type: nwload in the command line to load the nwexport plugin.
NOTE If SwitchBack needs to be available every time AutoCAD is run, nwexport can be added to the set of startup
applications in AutoCAD.
2 Once the CAD package is running, and nwexport has been started, return to Autodesk Navisworks.
3 Click Tools ➤ Global Options.
4 In the Options Editor, expand the File Readers node, and click the DWG/DXF/SAT option.
5 On the DWG/DXF/SAT page, check that the Convert Entity Handles option is selected.
6 Select an object in the Scene Area, and click Review ➤ SwitchBack.
The current Autodesk Navisworks camera view is taken back to the CAD package, and the same object is
selected. Selection of objects is done by entity handle.
NOTE If a Clash Detective tool is available, you can click the SwitchBack button on the Results tab.
7 Make the changes in AutoCAD, then save the changes.
8 Return to Autodesk Navisworks, and click Refresh
on the Standard toolbar to view the modified object.
NOTE Some objects cannot be selected in AutoCAD (for example, blocks) which may mean that running SwitchBack
may be unsuccessful with a given selected object. If this is the case, try selecting further up the object tree and trying
again.
