Drawing A Floor Or A Roof On A Different Plane

Intricate roofs have many parts that incorporate several of the basic roof designs such as a gable roof sitting atop a gambrel or variations of the gable valley roof design using one or a variety of different types of roof trusses also see our very detailed diagrams showing the different parts of a roof truss.

Drawing a floor or a roof on a different plane.

Keep it simple stupid. This means that you have an imaginary plane cutting through the building at an elevation of 4 feet above the floor. In the two examples shown below the wall plans are identical apart from the parapet wall in roof b yet the two roof shapes are quite different as indicated by the roof lines on the plan drawings. The plan is typically cut at a height of about 4 feet but the architect drawing the plan may cut it at a different height.

Also different architectural styles will use the same type of roof. For each offset angle or change in plate.
