The Plan, Profile or Multi-plot Windows can be exported to DWG, DXF or DGN; The graphical format (Linetypes symbols, labels and other) of the exported data is set to match the corresponding Window Options (View | Active Window Options). Label sizes are controlled by the current scale (label sizes will match the sizes shown in Print Preview).
This option will create an AutoCAD file with elevation data for all applicable entities. Any entities for which elevation is not appropriate will have an elevation of -9999.
If this option is not checked all entities will be created on elevation zero and curves will be exported as Autocad ARC entities.
