This function sends AutoCAD LT to CAD data which are changed by set_select_...() or delete_select..() after you executed select(). So you have to remove CAD data which selected by select() on AutoCAD LT before you execute update_select_data(). Concrete a method executes below example after you executed select() immediately.
example:command2("_erase _p ")

Caution:After you executed this function, you don't use get_select..() and set_select..() because LTCustomizer21 released memory for selected CAD data.
