When we love drawing, I believe we have the DNA of a geek.
We got to learn plenty of sketching techniques, tips and tricks to be able to draw from our imagination.
Today, I have prepared a very specific tutorial on How to draw sections on Spheres and Ellipsoids.
With this, you will be able to draw fruits sliced by a sword like in FRUIT NINJA!
Or anything else you could think of!
Imagine you have a Ninja sword,
and you are going to practice cutting anything that has a sphere or ellipsoid volume!
As usual, I made it easy to learn and practice.
So you can apply it now even if you are a beginner.
- 1. Master the basic movements of drawing
- 2. Go from a 2D circle to 3D sphere using ellipses
- 3. Draw the sections with oblique hatching
- 4. Draw contour lines to show volumes
- 5. Think of sketching as "Sculpting"
- 6. Experiment with different angles of "cut"
- 7. Imagine different objects you want to cut!
- 8. Use simple rules of geometry
- 9. Block a 30-minute session to practice
- 10. Try out Sketchbook Pro software

How to Draw Sections | Sphere + Ellipsoid
I have summed up the video in 10 points below to remember and practice.
Make sure to watch the video tutorial by taking visual notes.
That will help you to remember the drawing techniques forever.
1. Master the basic movements of drawing
Before starting, it’s great to warm up your hands by practicing the basic movements.
It is a great way to improve your drawing skills, on a sketching daily basis,
Focus on drawing circles and ellipses as these are foundational to more complex forms.
2. Go from a 2D circle to 3D sphere using ellipses
Try transitioning a 2D circle or ellipse into a 3D shape by drawing two perpendicular ellipses within the initial form. This is a crucial step in understanding volume and depth in your sketches.
3. Draw the sections with oblique hatching
Incorporate hatching into your sketching routine to indicate surfaces.
This will indicate your section.
IMPORTANT: Avoid trying to draw a half-watermelon directly.
Imagine the whole sphere as a watermelon, then cut in half!
4. Draw contour lines to show volumes
Utilize ‘Contour lines‘ when you’re sketching objects for better comprehension of their volume.
This Design sketching technique will help you visualize the object’s dimensions accurately.
5. Think of sketching as “Sculpting”
Approach sketching like sculpting.
Start with complete basic 3D forms (spheres, cubes, ellipses, cones)
then gradually cut them according to the design you want to create.
We use here a subtraction approach.
6. Experiment with different angles of “cut”
Experiment with different angles and sizes of cuts
while sketching an object from various perspectives.
That drawing practice enhances your spatial understanding skills.
7. Imagine different objects you want to cut!
Imagine different products, food… within each sketch (it could be a coconut, an orange, or a bowling bowl…).
This practice aids in developing creativity and attention to detail.
8. Use simple rules of geometry
For capturing complex shapes effectively,
learn geometric construction techniques that provide structure and accuracy to your designs.
Product design sketching becomes much easier than you think.
It is all about a succession of simple techniques that create complex drawings.
9. Block a 30-minute session to practice
Commit yourself to at least 30 minutes of daily practice for steady progress in design sketching skills over time.
- Turn on some Lo-Fi music.
- Keep your phone or any distraction away.
- Enjoy practicing drawing and experimenting like a Geek in his laboratory. :)
10. Try out Sketchbook Pro software
OPTIONAL:
Use tools such as Sketchbook Pro software to practice drawing on your graphic tablet.
