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.
Rumus:
h = s · sin(60°) = s · (√3 / 2) ≈ 0.866025 · s; θ ∈ {30°, 90°, 150°}Asal-usul Sejarah & Evolusi Ilmiah
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.

Bagian 04 — Panduan Menggambar
Panduan Langkah demi Langkah untuk 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.

Bagian 06 — Pertanyaan Umum
Pertanyaan yang Sering Diajukan (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.
