General Line XY Data	This field defines the coordinate of the line vertices. The underlying data consists of a series of (x,y) pairs. Each line is made up of a series of straight lines between the defined (x,y) pairs. This data is not displayed on the grid or property sheet. Coordinates of line vertices are included when you export line data to CSV files. There are two options available for exporting line coordinates. These are selected on the Select CSV Export Options Dialog using the Coordinate Arrays Format dropdown list. The options are: Packed - The data is exported as a series of x,y pairs. {389904.,111350.,390309.,111765.} Separately - the data is appended to the end of the row containing the line data. Each x and y value is in a separate (comma separated) field.	general_line_xy	Array		XY	3
