In our two worked examples we have made a wall and a roof truss. In this worked example, using these objects we now want to create a building

Brief

Using the wall and truss objects, and modifying where necessary, generate a model of a three-sided structure (4th side is open) with a pitched roof. The 3 sides of the structure are brick walls and should be keyed together where they join and have a flush face at the open edge. The brick structure should be 3m wide, 4m long and 3m high (nominal dimension), the roof slope should be 30 degrees. The roof truss beams are 40mm wide and 50mm tall, with a wall thickness of 3mm and a density of 7800 kg/m³. They should be equally spaced, no more than 1.5m apart and the minimum number of roof trusses should be used subject to there being at least 2. Cladding should be added to the roof, such that it touches on the apex and overhangs at the front, rear and sides by 50mm. The cladding is 10mm thick. Determine the size of the cladding panels, the mass of the roof trusses and the lengths of the individual beams, the number of bricks and half-bricks required and the volume of morter. Bricks are the standard size - 180mm long, 45mm high and 90mm wide
