B.Arch Curriculum · Semester 2

Architectural Graphics & Computer Studio

Drawing moves to the screen. Learn digital drafting from the ground up — the model-space world where you draw at full size, the language of symbols and hatches, and the CAD toolset of layers, blocks and precision input. Then document a set to standard — annotation, dimensions, revisions and plotting to scale — and build two projects: a coordinated plan-elevation-section set, and a full working drawing with its electrical layout. The digital companion to our Architectural Graphics I and Design Drawing courses.

Start with Unit I All student courses

This is the digital studio. It is the computer counterpart to two hand-drawing courses you should know first — the by-hand technical conventions in Architectural Graphics I, and the freehand, by-eye Design Drawing course. CAD automates the conventions; it does not replace the thinking those courses build.

Unit V · The point of it all

Working & Electrical Drawings

The project unit, and the point of the whole course: the working drawing set — the instructions a contractor builds from. We cover what a working set contains, the schedules and specifications that go with it, and then a services drawing every architect must understand: the electrical layout, with its IS symbols, points and circuits (NBC 2016 Part 8; IS 12032 Part 11; IS 732). We close on the Indian sanction set.

The syllabus

Five units, from the first command to the construction set.

Transcribed from the official B.Arch syllabus. All 5 units are live as full interactive lessons — with original diagrams, two live tools and a self-assessment quiz.

Unit 1 — Drafting Basics

Live

Introduction to digital drafting; from the board to the screen; vector vs raster; drawing at full size (1:1) in model space; the graphic language — representation and symbols for doors, windows, materials, glass and hatches (IS 962).

CO1

Unit 2 — Drafting for Architectural Design

Live

Geometry basics; creating tools (line, polyline, circle, arc); editing tools (move, copy, offset, trim, fillet, mirror, array); precision by coordinate entry, ortho and object snap; layers and ByLayer properties; blocks with attributes; associative hatches.

CO2CO6

Unit 3 — Drafting Documentation

Live

Composing the sheet in paper space; annotation, text and leaders; associative dimensioning and dimension styles; revision clouds and the revision table; plotting to scale with CTB/STB lineweights and PDF output.

CO3

Unit 4 — Mini Project

Live

Assembling a coordinated drawing set for a small building — plan, elevation, section and details — how the views relate, a working layer scheme, and the conventions of cut and seen, poché and callouts.

CO4CO6

Unit 5 — Project Work — Working & Electrical Drawings

Live

The construction document set: working drawings, schedules and specifications; the electrical layout with IS symbols, points and circuits (NBC 2016 Part 8); coordination of services; and the Indian sanction / submission set.

Course outcomes

What you should be able to do after completing all five units (CO1–CO6, from the syllabus).

Understand

Understand digital drafting basics and represent doors, windows, materials and fittings with standard design symbols.

Apply

Draft architectural geometry with CAD creating and editing tools, precise coordinate input, layers and properties.

Create

Produce drawing documentation — sheet layout, annotation, dimensioning, revisions and plotting to scale.

Create

Create and present a mini-project as a coordinated set — plan, elevation, section and details.

Create

Execute a detailed project including working drawings, schedules and an electrical layout.

Apply

Apply CAD standards and studio discipline — layers, blocks and sheet organisation — across a complete project.

A layer-toggle demo

Switch walls, doors, dimensions and furniture on and off on a sample plan — see how one model makes many drawings. In Unit II.

A scale → sheet calculator

Pick a building size and a scale and find the plotted size and the smallest A-sheet that fits. In Unit III.

The rest of the drawing toolkit

Architectural Graphics I

The by-hand technical side — instruments, projection and measured drawing. CAD automates these conventions, so learn them first.

Design Drawing course

The freehand, by-eye companion — sketching, observation and perspective that no CAD tool replaces.

Architectural Design I (Studio)

Where these drawings go to work — designing and presenting a scheme.

Building Materials & Construction I

What your details and working drawings actually describe — how a building is put together.

Scale & Proportion tool

Check scales and ratios interactively while you set up a sheet.

Studio tools & calculators

Free interactive tools — areas, costs, sun-path and more — to feed your drawings.

Topics and outcomes follow the published B.Arch syllabus (L1 · T0 · S3; 150 marks). Every diagram and both interactive tools are original Studio Matrx work; the facts and standards are cross-checked against the cited sources (Indian Standards, the National Building Code and the CAD literature). The course is vendor-neutral — the ideas apply in AutoCAD, DraftSight, ARCHICAD or any CAD tool. Photographs are illustrative.

From your first line to a set that builds.

Digital drafting, the CAD toolset, documentation, and a full working and electrical drawing set — read the five units, try the layer demo and the scale calculator, and test yourself.
