I have Architecture 2009 installed on both my PC and laptop although I have never drawn with the software on my laptop. I am currently have a few technical issues with my PC and need to complete a drawing on my laptop software. When I am drawing a room layout in plan view the walls drawn at @ 90 degrees do not automatically join as a continuous wall but only join at the inside corners. Is there a default setting I need to change to allow me draw continuous wall layouts in plan view ??? Many thanks for your response
