Have you ever wished you had a single button you could press and bring up the nifty little osnap popup? This guide will show you how to remap button 7 on your Logitech G5 laser mouse to open the Osnap Popup menu in Civil 3D 2008. Your mileage may vary when setting up a different mouse or different button, but the same basic technique still applies.

1. Open the Logitech Setpoint software (mine was listed Mouse and Keyboard Settings under the Start Menu.
2. Under section 1a (Select Program), click the Manage Programs button.
3. In the Manage Programs dialog box, click the Add button and browse to the C:\Program Files\AutoCAD Civil 3D 2008\acad.exe file and click Open.
4. Now under section 1a (Select Program), use the drop-down to select AutoCAD Application.
5. Under section 2 (Select Button), choose button 7 (Sensitivity Increase).
6. Under section 3 (Select Task), click the radio button for Keystroke Assignment.
7. Under section 3a (Specify Keystroke), set focus to the Keystroke box and hit Cntrl+L on your keyboard.
8. Click on the Apply button, and then the OK button.
9. Now open one of the Civil 3D 2008 applications and enter CUI at the command prompt.
10. In the top-left window, find Keyboard Shortcuts and expand that group to find Shortcut Keys. Pick that.
11. Now in the top-right window it will list all of the accelerator keys within that group. Scroll down thru the list until you see Cntrl+L in the Keys column and select that.
12. Now in the bottom-right pane (Information), set the Name to Osnap Popup for Mouse, leave the Descriptin blank, and change the Macro to $P0=SNAP $p0=*
13. Hit Apply, then OK and let Autocad do it’s thing.

If you have more than one Autodesk product installed, you’ll need to repeat this procedure for each.

Enjoy!
