Working Drawings: Orthographic Projections and Sectional Views

Working drawings show buildings exactly as they are, drawn to scale from different angles. Orthographic projections mean drawing the front, side, and top views of a building on flat paper, just like looking at it from different directions. Think of it like photographing a house from the front, then from the side, then from above—all these images together give the complete picture.

Sectional views slice through the building imaginary, showing what you'd see inside if you cut it with a knife. For example, a section through a typical Lagos residential apartment shows the floor levels, room heights, and wall thicknesses when viewed from the side. These drawings help builders understand exact measurements, material placement, and construction details.

Sectional views are particularly important because they reveal hidden parts—like roof structure, foundation depth, and internal arrangements that regular front views cannot show clearly.

💡 Exam tip: Always label your sectional views with the cutting line, show all dimensions clearly, and remember that sections must match your elevation drawings perfectly.
