Map Windows within the program are also capable of accepting data through a drag and drop operation. This can be a very convenient way of specifying TIN datasets for use in the program. The program can accept one or more TIN files dropped onto a Map Window. If more than one is dropped, the program aggregates them together. By default, the program replaces the currently selected TINs in the Map Window with the new dropped in ones. However, if the keyboard 'Ctrl' key is held down during the drop action, the TIN files will be added to the TIN datasets already present in the Map Window. Be aware that dropping TIN files on the Map Window will change/disable many of the TIN filtering options set for the Map Window. In general, it will leave the filtering options set as before but will disable using the filters.
