Hello, there are not many updates, checking the current functions I have realized that many of the functions only run when using TIN, if one closes the drawing can no longer use other functions, since many of them use variables that when closing the Drawing left in NIL or empty, an example of TL variable, ie a function like DEMOZ does not work if not used TIN, every time we use DEMOZ we must use TIN again, it would be nice to be able to solve this, thanks
