A section cut symbol marks where a drawing slices through a building, which direction the viewer faces, and where the resulting section is drawn. It combines a cutting line, a direction arrow, and a bubble carrying the section number over the sheet number, so a reader can move from plan...
A reflected ceiling plan is a drawing that shows the ceiling of a space as if a mirror were laid on the floor and the ceiling reflected down onto it. Because of that mirror logic, the drawing keeps the same orientation as the floor plan, so lights, grid lines and...
Poche in architecture is the filled area of a plan or section where the cutting plane passes through solid material, usually walls, columns and floor slabs. Rendering that mass in black or a dense tone pushes it into the background, so the rooms left between it read instantly as usable...
A floor plan is a horizontal section through a building, drawn as if a cutting plane passed through the walls about 1.2 metres above the finished floor and everything above it was lifted away. It shows the size, shape and relationship of rooms, along with doors, windows, stairs and dimensions....
A site plan is a scaled drawing that looks down on an entire property and shows how a building sits within it. It maps the parcel boundaries, setbacks, existing and proposed structures, driveways, parking, landscape and levels. Planning departments treat it as the record of where construction is allowed to...
A window CAD block is a reusable drawing symbol that represents a window opening in plan, elevation and section. In plan it shows the wall break with frame, sash and sill lines. In elevation it gives the sash layout and the opening direction. In section it cuts the head, jamb...
Architectural drawing scales describe the ratio between a measurement on paper and the real building. A 1:50 scale means 1 unit on the drawing equals 50 units in reality, so 1 cm represents 50 cm. At 1:100, that same centimetre stands for 100 cm, giving you a smaller, more compact...
Line weight in architectural drawing is the relative thickness or darkness of a drawn line, used to create visual hierarchy on a sheet. Thicker lines pull elements forward and mark what a section cuts through, while thinner lines push detail back. Reading a plan or section depends almost entirely on...
A title block on a drawing is the framed panel, usually in the lower right corner of a sheet, that records who created the drawing, what it shows, its scale, date, sheet number, and revision history. It gives every sheet a unique identity so drawings stay organized, traceable, and easy...
A stamped (sealed) architectural drawing is a construction document that carries the official seal and signature of a licensed architect, certifying that the drawing was prepared by or under the responsible control of that architect. The stamp signals legal accountability for the design and is usually required before a building...
CAD layer standards are the unsexy foundation of architectural drawing, and they are also the difference between drawings that print cleanly and drawings that take three times longer to produce than they should. Most architecture students learn AutoCAD or its alternatives by following studio assignments, picking up bad habits along...
Section drawings reveal architecture in ways no other drawing can. The relationship between floors, the negotiation of structure with space, the play of light through a building's volume, the way ground meets building meets sky, all become visible in section in a way that plans, elevations, and renders cannot show....
Hand drawing vs digital architecture is a question most architecture students wrestle with in their first or second year.
When it comes to bringing architectural visions to life, detail drawings are the unsung heroes. They’re the bridge between bold ideas and tangible structures, offering the precision and clarity needed to ensure every element fits perfectly. Without them, even the most brilliant designs could falter during construction. We rely on...
