I am exporting a surface to a LandXML file so I can import the surface in SMS 11.0. It appears the the northings and eastings are reversed. The landxml points are listed as a (northing, easting, elevation) pr (y,x,z). The way the surface is displayed in SMS looks to be (Easting, Northing, elevation) or (x,y,z). Has anyone else experienced this problem? Or is there a way to change the way the coordinates are read? I am using Pennsylvania State Plane Coordinates. Thanks for your help.
