I am trying to import a LandXML surface into my project. However, when I click the "LandXML" button in the "Import" tab, absolutely nothing happens. The command _AeccLandXMLIn appears in the command line, but there is no dialog box and no further action from Civil3D. Any ideas how I can get this to work?
I ran into a similar problem with the normal "Open File" dialog box, and had to run a FILEDIA command to turn that dialog box back on. Is there a command like that to turn on and off the Import LandXML dialog box?
