Asas Geometri dan Formula Koordinat

60° Equilateral Rhombic Geometry

Isometric projection represents 3-dimensional objects on a 2D plane by foreshortening all three principal axes equally at 120° angles to one another. The grid consists of vertical lines (90°) intersected by parallel diagonals inclined at +30° and -30° from the horizontal.

Formula:
h = s · sin(60°) = s · (√3 / 2) ≈ 0.866025 · s; θ ∈ {30°, 90°, 150°}

Asal-usul Sejarah & Evolusi Saintifik

Isometric projection was formalized in 1822 by Professor William Farish of Cambridge University. Farish recognized that mechanical engineers needed an optical drawing method that preserved measurable linear scale along all three axes without perspective foreshortening.

Bahagian 04 — Tutorial Melakar

Panduan Langkah demi Langkah Melakar pada Kertas Isometrik

LANGKAH 01

Orient the Isometric Axes

Identify the three primary axis directions: vertical for height (Z), +30° right for length (X), and +30° left for width (Y).

LANGKAH 02

Construct the Bounding Box

Draw the overall envelope of your object along the primary isometric lines using direct measurement increments.

LANGKAH 03

Plot Non-Isometric Lines via Offsets

Non-isometric edges (such as roof slopes or bevels) cannot be measured directly. Locate their endpoints along isometric lines, then connect them.

LANGKAH 04

Draft Isometric Circles (Ellipses)

Construct circles on isometric planes using the four-center rhombus approximation method or isometric ellipse guides.

Bahagian 06 — Soalan Lazim

Soalan Lazim (FAQ)

What is the difference between isometric and trimetric grid?
In an isometric grid, all three coordinate axes are spaced at 120° and scaled equally (1:1:1). In dimetric and trimetric projections, axes use differing angles and scale factors to accentuate specific viewports.
Can I sketch directly on this isometric grid online?
Yes! Click 'Open in Virtual Studio' to draw 3D diagrams directly in your browser with line angle locking and vector SVG export.
What spacing is recommended for isometric paper?
5 mm spacing is the international standard for mechanical engineering notes and student drafting. 10 mm spacing is ideal for larger architectural models.
How are circles drawn on isometric paper?
Circles project as ellipses with an aspect ratio of approximately 1.732 : 1. They are drawn using a 4-center circular arc approximation inside an isometric rhombus.
