Arranging and Snapping Room Boxes

To arrange the room boxes into your design simply pick up each box and drag it into position, and drop it.
If you position the boxes so that are aligned closely edge-to-edge the dropped box will "snap" to the adjacent box with edges aligned, and if possible with corners aligned.
It is a good idea to turn Off Dynamic snaps while you are arranging your boxes, since the two types of snapping may conflict in some instances.
You can resize the boxes while they are selected by using the blue handles on the edge of the selector. If you hover over the edge of an adjacent box while resizing the edge you are adjusting will snap to align with the edge you are hovering over.
For best results, it is suggested that you put small ancillary rooms within larger rooms e.g. bedrooms.
Once you are done arranging your rooms, click the Build House button.
