The Square & Cube

⏱️ 5 min 📊 Beginner 🖌️ Tool: Pen
Square and cube drawing practice

Why this matters: The square is the foundation of every 3D shape. By learning to draw a perfect square and then turning it into a cube, you're taking your first step into the world of perspective and three-dimensional drawing. This skill is essential for everything from architecture to character design.

🎯 A gentle reminder: Your square doesn't need to be perfectly measured or your cube perfectly proportioned. What matters is understanding the relationship between 2D and 3D. Wobbly lines and uneven angles are part of the learning process – embrace them!

Step 1 Step 2 Step 3 Challenge

1 Setup Your Canvas

Look to the right panel – that's your live drawing app. Make sure the Pen is selected. Set your brush size to 3 or 5 (click the gear icon on the right toolbar). Pick a dark, bold color like #1A1A1A or #2D3436.

You might also want to turn on the Grid (Settings → Show Grid) – it can help you keep your square proportioned!

💡 The app auto-saves every stroke. Don't worry if you refresh the page!

2 Draw the Perfect Square

Start by drawing a square in the center of your canvas. Try to make all four sides roughly equal length.

  • Use your straight line skills from the previous drill!
  • Draw the top line first, then the bottom, then connect the sides.
  • Don't worry if it's not perfect – practice makes progress.

Pro tip: If you're struggling, draw a horizontal line and a vertical line that cross in the center, then build your square around them. This gives you a reference point.

📐 Pro Tip: A square is just four straight lines of equal length. If yours looks like a rectangle, that's okay – you're learning!

3 Turn It into a Cube

Hit Clear on the right toolbar. Now draw a square again, but this time, turn it into a 3D cube!

  • Draw your square first.
  • Add 3 diagonal lines going up and to the right from the top-right, bottom-right, and top-left corners.
  • Connect the ends of those diagonal lines with straight lines to form the back of the cube.
  • Now you have a cube!

Try this: Try drawing the cube from a different angle – make the diagonal lines go up and to the left instead.

🧊 Pro Tip: The key to a convincing cube is making all the diagonal lines parallel and roughly the same length. And remember – this is just practice!

4 🏆 The Challenge

Click "Clear" on the right toolbar. Now set a timer for 90 seconds.

Your mission: Draw as many cubes as you can – but here's the twist – make each one from a different angle.

  • Cube 1: Lines going up and to the right.
  • Cube 2: Lines going up and to the left.
  • Cube 3: Lines going down and to the right.
  • Cube 4: Lines going down and to the left.
  • Repeat!

Remember: Every artist started with wobbly squares and wonky cubes. The more you practice, the more natural it becomes. Keep going!
