3D Modeling Self-Guided Lesson
A TMI (think, make, improve) activity.
Intro 3D Modeling
3D modeling is the process of drawing an item that is three-dimensional. As opposed to two-dimensional images that use only width and height to describe an image, 3D modeling uses width, height, and depth to allow viewers to perceive the spatial relationship between objects, through our depth perception.
You may be most familiar with 3D modeling when creating items to be printed with a 3D printer, but 3D modeling has many additional uses including video games, movies/animation, architecture, illustration, engineering, and commercial design.
The following video shows some 3D modeling concepts and terms.
3D MODELING CONCEPTS
Think:
Step 1:
- Research: Check out Sketchfab or Thingiverse and explore different 3D models.
Step 2:
- Brainstorm what type of simple 3D model you would like to make.
- Find a physical object (from your classroom) or a 2D photo of an object (from the internet) or make a sketch of your object.
- Looking at the object or photo, determine what shapes, lines, textures, or colors you will need to use to create the 3D model.
Make:
Step 3:
- Grab a computer and create an account/log-on to tinkercad.com
Step 4:
- Click "Create a New Design" under 3D Designs and start creating your 3D model.
- This is a trial and error process - you may not get it right the first time. Don't give up!
Step 5:
- When your design is complete, "Export" your design and choose the .STL file type.
Troubleshooting & Help:
- If you are stuck:
- Learn how to use Tinkercad: https://www.tinkercad.com/learn/designs
- Google/Youtube it.
- Email jacie.milius@unl.edu with your question.
Improve:
Step 6:
- Show your model to someone else, ask them for feedback.
- Determine what is good, and what can be better
- Make changes to your 3D model (you may need to go back to Tinkercad, make adjustments, and complete the export and upload process over)
Share. Process. Generalize. Apply.
The sky is the limit when it comes to 3D modeling, and the applications for models are endless. Think of one career that uses 3D modeling, and imagine yourself doing that when you graduate.
