Disabling Map 3D Functions

Increase Performance!

If you are struggling with performance and/or stability in Civil 3D, and don’t often use Map 3D commands, disabling the Map 3D auto loading on startup may offer some quick relief.

The following link, Disabling Map 3D Functions, is to an Autodesk-published technical solution (TS13390398) containing instructions and files necessary to toggle on/off the auto loading of Map 3D files on startup of Civil 3D. 

Changes occur to the User registry settings, so adequate user permissions are required.

  1. Save and unzip the attached file to a specific location on your computer
  2. Right-click on Civil3DMapControl.wsf, and select “Create Shortcut”
  3. Right-click on the Shortcut icon created, and select “Properties”
  4. On the General tab enter an appropriate name, such as, Civil 3D (+ Map)
  5. On the Shortcut tab, make the appropriate addition to the end of the Target field (place a space after the “…\Civil3DMapControl.wsf” entry):

For Civil 3D 2009: //Nologo /2009 /Disable

For Civil 3D 2010: //Nologo /2010 /Disable

  1. Repeat steps 2-5 to make another icon to enable auto loading.  Substitute Enable for this second shortcut.
  2. If auto loading is disabled, you can always manually load all the Map files during a current session by typing “_MapStartWSpace” on the command line.

Do not try to run Map commands without doing this first, or Civil 3D will crash.  The next time you start Civil 3D, it will still disable auto loading.
