Last Lesson
In the last lesson, we learned how to maneuver through the space in an Inventor file. Now, we will learn about how to fix shapes that won't extrude properly into 3D.
Evaluation
You will be evaluated for this lesson based on your ability to:
- make non-visible and extruded sketches visible.
- edit existing sketches.
- repair shapes to make them extrudable.
Demonstration
Watch the video below. You can and should pause it as needed in order to facilitate taking notes. (You may also rewind it and rewatch sections.) Afterwards, you will discuss it with a partner and as a group. If you finish early, download the file below the demo video, edit each of the three sketches, and repair the shape in each sketch to make it extrudable. Then, extrude it.

You Do It Alone
Troubleshooting RWE
- Log into Google Classroom.
- Go to the assignment tab. Select the "Troubleshooting Shapes RWE"
- READ THE RUBRIC CRITERIA.
- Download the file below, and follow the instructions.
- Make each sketch visible.
- Edit each sketch, and repair the gap at the lower left corner of each square using one of the three methods. NOT ALL METHODS WILL WORK ON ALL SHAPES. If one method does not work, try another.
- Extrude each shape.
- Take a screenshot from the home/angled/isometric view, and add it to the assignment. (If you don't know how to take a screenshot, google how to use the snipping tool.)
- Submit for scoring.
- Move onto the extension activities below.

Extension Activities
- Use the line tool to create your own name in block letters. Extrude it, using these tools to repair any shapes that cannot extrude properly.
- Create a set of farm animal shapes, and extrude them out. Use these tools to repair any shapes that cannot extrude properly.
