Wall Labels are uniquely numbered for every wall (or part of a wall) for each room shown. They are shown red in colour with a white number until construction materials have been selected, yellow in colour with a black number when pre-selected immediately prior to clicking on them to enter the construction materials database and grey in colour with black numbers after construction materials and (if applicable) other details such as exposure, doors and windows and surface colour etc., have been entered.
When a drawing is zoomed to minimum size and especially when much fine dimensional detail has been entered then the wall labels can obscure parts of the drawing; making it difficult to see. A facility to 'toggle' the wall labels on or off has therefore been provided. Simply click on - .
