• Enter a description for every room. This description is useful when exporting the input data.
• Select the shape of the room: rectangular, triangular or a part of a circle.
• For rectangles enter the length, width and height. The second height is for rooms with a roof that is not flat. For such rooms the first height is the height of the lowest wall and the second height is the height of the tallest wall.
• For triangles enter the length of one of the sides in the field Length. Then enter for the field Width the length of the line from the opposite angle perpendicular on this side. This is the height of the triangle. This height of the triangle should not be confused with the height of the room.
• If the shape of the room resembles a part of a circle then enter its radius under the field Length. Enter for example 0.5 into the field Width if the room resembles half of a circle.
