After you import a surface into your model, there may be areas of the surface that you do not need, or that appear to have errors. You can trim the surface model so that you focus on only the area you want to work with.
Optionally, ensure that all ASC tiles are loaded, as they make up a large area. A site may be located at the junction of four tiles. Best practice is to load all the tiles, then pare it down so that you are focusing on only the area that you want. Save the pared-down area of ASC tiles as an InfoDrainage file. Then, import the new .iddx file.
IMPORTANT: When defining the trim surface, indicate the surface you want to keep, not the piece you want to discard.
