The raster on the page changes from symbol presentation to text presentation when a text object is selected and vice versa.
The text can be presented in UniCode characters (6 x 12 pixels). The total size of the presented white area (page) represents the visible part of the LHMI display without the header line.
The visible display for a single-line diagram is organized in a raster of 9 x 7 (columns x rows). Each symbol (presented in 15 x 15 pixels) included in the drag-and-drop method must be dropped into a raster box.
The description text for an apparatus object can be placed in all four directions around the symbol. The description is part of the apparatus object. It is possible to place the symbols without the assistance of Snap to Grid and manually change the position coordinates.
