How can I get CoordinateSystemCode?

[Anonymous]

I get a TinSurface and I want to Export it to a .tif File by ExportToDEM( string fileName, string coordinateSystemCode, double gridSpacing, ExportDetermineElevationType deteElevBy ).But it always shows me this mistake "The coordinateSystemCode is not supported." I don't what can I fill in it.What can I fill in it?

you would need to input the coordinate system code for the surface.... if your drawing is assigned to a coordinate system, go to the drawing settings and use the code shown there.

Use the Toolspace.

1. Right click on the name of your surface and select Export to DEM from the shortcut menu.
2. In the Export Surface to DEM window, you'll need to Name your export and a folder to save it.
3. In the same Export to DEM window you may also choose 1) Coordinate zone, 2) grid spacing, and 3) determine elevations by.
4. OK to export. 

1-Right click the Name of surface in Toolspace.

2-Name your DEM and a folder location.

I know this way but I want to realize the method in C# and now in C# I need to fill in the right CoordinateSystemCode but I try many times,it always throws the exception " The coordinateSystemCode is not supported.".I want to know how to get the coordinate's coordinateSystemCode.

like this,what is the coordinateSystemCode corresponding to this coordinate zone?How can I know it?

Nick,
As @Anonymous mentioned, in Drawing Settings look for "Selected coordinate system code:"

Nick,
What version C3D are you using? Are you current on updates? Can you post your drawing?

@Anonymous Look in the SettingsUnitsZoneClass.

I know the reason why it throws a mistake.Because not all codes are supported,only a few of them can be used!!!
