This is explainer 1 of 8 in this series

This series includes:

  1. Get tooled up for this explainer series
  2. Navigate the Tinkercad interface, add 3d objects to the workplane and rotate & scale them
  3. Create a coffee mug in Tinkercad
  4. Export a coffee mug from Tinkercad in OBJ format
  5. Navigate the Kenney Shape interface and edit built-in objects
  6. ‘Trace’ a Space Invader image in Kenney Shape to create a 3d object and export it in OBJ format
  7. Create a new Unity project and import the objects created in Tinkercad and Kenney Shape
  8. Import a free Unity coffee shop asset and place our 3D objects in the scene

The Software

This series of explainers uses three separate programs:

Tinkercad for introducing basic 3d navigation, scaling and rotating shapes, combining them and exporting 3d objects. Tinkercad is completely free and runs in a web browser. Get yourself a free account now and be ready for explainer two!

A 3D design software interface shows a yellow mug with "retro cafe" text on its side. Various design tools and shape options are visible on the right side of the screen.

Kenney Shape, for ‘tracing’ a 2d image to turn it into a 3d object and export it. At time of writing Kenney Shape costs less than £5 / $5. We’ll be creating and exporting a 3d Space Invader in explainers five and six:

A digital interface displaying a pixelated space invader design in grey on a transparent grid, with editing tools and options at the top and bottom of the screen.

Unity for importing 3d objects, assembling them into a scene and applying simple textures and lighting. Unity is FREE for personal use. We’ll start assembling our Retro Cafe in explainers seven and eight:

A neon sign reading "Retro Cafe" is displayed beside a coffee machine and several mugs. The yellow and orange mugs have the text "retro cafe" printed on them.
An image of a café counter with a "Retro Café" neon sign on top and pixelated green alien art inspired by Space Invaders on the front. Various retro and gaming-themed items are placed on the counter.

3D Objects created in this series

Using a general theme of ‘Objects for a Retro Cafe’, once we’ve got to grips with Tinkercad we’ll use it to create a coffee mug from scratch, complete with branding:

A 3D design software interface shows a yellow mug with the text "retro cafe" on it. Various 3D shape options are displayed on the right sidebar.

We’ll also make a ‘hole’ in the mug to create a ‘realistic’ design that could be 3d printed or used in 3d games:

A 3D modeling interface displays a yellow mug with "Retro Cafe" embossed on it. Basic shape tools are visible on the right panel.

We’ll ‘trace’ a 2d image of a Space Invader in Kenney Shape to turn it into a 3d object…

A digital interface displaying a pixelated space invader design in grey on a transparent grid, with editing tools and options at the top and bottom of the screen.

…while having fun with ‘Grandpa’ Invader and Kenney Shape’s built-in retro objects:

A white, blocky, 3D representation of an 8-bit video game alien character on a black background.
A pixelated spaceship design with various colored blocks and alphanumeric symbols displayed on the screen of a design tool interface.

Finally, we’ll bring our saved objects into Unity and start blocking out a 3d cafe scene!

A colorful logo with the word "Pixels" in bold, white, and orange letters, above ".cool" in red cursive, outlined with rainbow layers and yellow rays in the background.

The pre-requisities

This is a BEGINNER explainer series, starting with beginner-friendly software. You need to have a basic knowledge of using Windows, downloading and installing software to follow along with this series. Tinkercad and Kenney Shape are beginner-friendly programs. Unity is a complex application and is not recommended for new computer users. For introductory courses and videos for Unity, check out Unity Learn

Why would I do this?

We need the right tools for the job! We’ve selected Tinkercad as it’s completely free and offers progression routes into more sophisticated software including Fusion360 and Maya as your skills grow and you choose to specialise.

Kenney Shape takes an unusual approach to 3D modelling, by mirroring the building processes of ‘block’ systems including Lego and Minecraft. It’s fun to get started with, particularly if you like working with stylised / low-poly 3D objects.

Unity is a powerful realtime 3d engine used to create professional renders, animation and 3d games. Along with Unreal, it has a huge online community of users ready to help!

Good to know

As mentioned in the explainer, it’s best to use a keyboard and mouse as you start your journey with 3D. If you’re using a laptop, it’s tempting to use the trackpad, but you’ll find this limits you as you graduate to professional software. For this reason, we recommend purchasing a separate mouse…

Any modern mouse will work – It just needs standard left and right buttons and a central ‘wheel’, as below. There’s no need to spend more than 10 GBP / 10 USD unless you want to – Just check reviews before purchase. The explainers in this series assume you’re using a keyboard and mouse, so it’s worth the small investment 🙂

Where to next?

We’re just getting started! In the next explainer we’ll open Tinkercad and start learning the interface.
