Import Layer Filter

Just a note for those who use Layer Filters to help organize layers.  AutoCAD Civil 3d doesn’t automatically load the file, but it is easy to fix.

For AutoCAD Civil 3d 2011, find the following registry key and add the AECLayerManagerEx.dll as the ADT setting.  It’s blanks by default.

[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R18.1\ACAD-9000:409\Applications\AcLayer\Extensions]
"ADT"="AecLayerManagerEx.dll"

I covered the 2009 version here.   Hope this helps!
