How to hide/show the room measures?

Click on the Settings button. Uncheck both the 'Show dimensions' and the 'Show room size' fields and click on 'Save'. The measures are hidden now. 


When you click again on 'Show room size', the total square meter/feet for each room will be shown. Also in the down left corner you can see the total square meters/feet of the plan. 

Uncheck again the 'Show room size' and click on the 'Show dimensions' - only the length of the walls are now visible on the plan.
