The Export to 12d (Catchments) menu item automates the process of exporting data to 12d without requiring the macro module. This function exports the subcatchments (with small polygons dissolved) and longest flow paths to 2 x 12d ascii files and a .12dMap file which lists the files and their locations. The tool is designed to be used in conjunction with a macro by EXDS to aid direct integration between 12d and CatchmentSIM. The 12d course at the CatchmentSIM training site has more information.
