To get started in design sketching with confidence, I created the Designer Starter Kit for you to download: https://www.thedesignsketchbook.com/sign-up-and-receive-the-ebook-the-designer-starter-kit/
Want to level up your industrial design sketching and build effortless 3D vision from imagination?
Welcome back to the basics! In this tutorial, we break down how to draw boxes and cylinders intersecting in perspective step-by-step.
You'll learn:
How to find the center and edge midpoints of a square in 2D and 3D perspective
How to construct ellipses correctly using touch points and the minor axis
How to decompose shapes and carve out hollow tunnels using Boolean subtraction
How to transition from rigid construction lines to fast, loose sketching focused on accuracy over perfection
TIMESTAMPS
00:00 - Introduction & Hand Warm-Up
00:21 - Why Boxes and Cylinders Belong Together
00:47 - Step 1 & 2: Finding the Center and Edge Midpoints in 2D and Perspective
01:40 - Step 3: Drawing the Ellipse & Understanding the Minor Axis
04:32 - Step 4: Decomposing the Cylinder & Box (Volume vs. Mass)
06:00 - Step 5: Assembling a Cylinder Inside a Box & Projecting Points
11:08 - Step 6: Drawing a Cylinder as a Hollow Tunnel
15:13 - Step 7: Freehand Practice & Moving to Fast Sketching (Low Fidelity)
18:16 - Recap & Final Outro
