Architectural drawings can be devoted to depicting an overview of the building (i.e., an elevation), or they can focus on a particular element (a detail).
- Architectural drawing are made according to a set of convention, which includes particular views like floor plan, section, sheet sizes, units etc.
- Architectural drawing are use by architect to develop their design ideas to clients and also to communicate ideas and concepts.
6) Purpose of Architectural Drawing

- To communicate ideas and concepts.
- To make a record of a building that already exists.
- To indicate overall appearance of structure and minute details.
7) How to make Architectural Drawings
- With the Help of Drafting tools.
8) Drafting Tools
It consists of :
- Drawing board/ Drafting Table
- Parallel Bar
- Set – square (30/60 & 45/45 & adjustable)
- Sheets (of various sizes)
- Tracing paper
- Graph paper/ Square book
- French Curves
- Pencils (of different grades)
- Sand Paper
- Adhesive Tape
- Roll and Draw
i) Drawing Board/ Drafting Table
- The drawing board is an essential tool.
- Paper will be attached and kept straight and still, so that the drawing can be done with accuracy.
- Paper could also be secured to the drawing board with pins , C-clamps or adhesive tape.
- It can also be adjusted to different angles for the ease of the user.
ii) T- Square
- A T-square is a straightedge which uses the edge of the drawing board as a support.
- It is used with the drafting board to draw horizontal lines and to align other drawing instruments.
iii) Parallel Bar
- A parallel bar is attached to drafting table/ drawing board with the help of clamps and thread.
- The bar moves up and down on thin wire.
- The parallel bar is easy to use.
- Helps in supporting the set square for taking vertical measurements.
iv) Set – Square
v) Roll & Draw
viii) French Curves
- Architect’s scale is a scaled, three-edged ruler which has six different scales marked to its sides.
- They are of two types : Metric scales and Feetric scales.
- A typical combination for buildings details is 1:10, 1:20, 1:50, 1:100, 1:25, 1:75 and 1:125.
x) Protractor, Eraser & Cutter
- Wooden “Drawing” pencils are specially made to allow for the drawing of lines at different thicknesses or darkness’s.
- The “HARDNESS” or “SOFTNESS” of the lead determines the darkness or thickness of the line.
- Hard leads provide “light” or “thin” lines.
- Soft leads provide “dark” or “thick” lines.
- A good thing to remember:
- A B grade means the core has more graphite, and will make a bolder, darker line, and also be a little smudgier than a light pencil.
- An H grade means the core has more clay, and will make a lighter, finer line, and will be less smudgy than a dark pencil.
- 6B – Very soft for shading and rendering of pictorial views.
- B – Soft for drawing thick “border” lines on title blocks and drawing sheets.
- HB – Medium thick lines for freehand sketching.
- H – Medium thick lines for freehand sketching or lettering or drawing visible edges and outlines of surfaces.
- 2H – Hard thin lines for drawing hidden lines to show hidden surfaces or interior details.
- 4H – Hard thinner lines for drawing center lines and locating centers of circle and arcs or the axis of a cylinder.
- 6H – Hard very thin lines for drawing construction or layout lines and guide lines for lettering.
