Hello, There are four options to determine the area to be drawn in this section. These are Screen, Drawing limits, Limits, and Window. If the screen option is selected, the visible part of the drawing area on the screen, if the drawing borders are selected, the part within the defined drawing borders, if the limits are selected, all the drawings are drawn. If the Window option is selected, the area to be drawn from the Select Window dialog is framed. You can get support by calling our Istanbul office. Take it easy, good work..
