Civil 3D Double Click Customization

Is there a Civil 3D object that you would like to double click and run a specific command?  if so, read on.  (This works for AutoCAD commands too.)

Try double-clicking an Alignment.  The AutoCAD properties palette appears.  What if we want the Alignment Properties dialog instead?  Or if you want the Feature Line Quick Elevation Edit tool to be run when you double click a Feature Line.

Edits to the CUI file are required.  Please do yourself a favor and create a partial CUI file and make these edits in there.  And while you’re at it, save this file somewhere like My Documents.

1.  Determine the object name.  Run the LIST command and select the object.  The object name will be shown.  Mine is AECC_ALIGNMENT.
2. 
3. Run the CUI command.  The double-click assignments are stored in the CUI file.
4. Right-click to add a new double-click action.  Name it something like Alignment Properties

5. On the right half of the CUI editor, enter the appropriate object name.

6. Find the appropriate command in the bottom-left window.  In this case, Alignment Properties.  Drag it onto your new double-click action.

7. Close the CUI editor.

8. You’re done!  Double click the object and the command will be run.
