I am new for Sweet Home 3D. When I make a base plan and creating walls in one go by clicking several corner/point of wall, they joined each other. But, when I create another separate wall I can't able to join it with my base plan or any other wall. What should I suppose to do.
In the picture I have created Walls 1,2 and 3 in one go by clicking at each corner and double clicking at end. Then I create a separate wall 4 and want want to join it with wall 2 at red circle.
