This chapter looks at the advanced features of GiD in terms of expandability and total control. Using the Tcl/Tk extension you can create script files to automatize any process created with GiD. With this language new windows and functionalities can be added to the program.
For more information about the Tcl/Tk programming language itself, look at www.scriptics.com http://www.scriptics.com.
If you are going to use a Tcl file, it must be located in the Problem Type directory and be called problem_type_name.tcl.
