Learning Targets
- Identify a closed sketch profile.
- Use extrusion to create a 3D solid.
- Check extrusion distance and direction.
IED Unit 2 • Lesson 2.6
Extrude Basics
Focus question: How does extrusion turn a sketch into a solid part?
Mission Briefing
Today’s Plan
Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Turn a Closed Sketch into a Solid.
Success Looks Like
Your 2D sketch becomes a clean 3D feature with intentional depth.

Opening Prompt
Why does an extrusion need a closed profile?
Connect your response to the decision, evidence, or quality standard required for Turn a Closed Sketch into a Solid.
Reveal: useful CAD thinking move
A closed profile gives Fusion a clear region to turn into a solid feature. Open geometry usually cannot form a clean solid extrusion.
Core Skill
What We Are Practicing
Extrude adds depth to a closed profile.
Extrude distance controls thickness, length, or height.
Extrude direction matters for assembly and print planning.

Fusion 360 Extrude Cut & Extrude Basics You Must Know
Review profile selection, extrusion distance, direction, and operations before creating the first solid feature.
Pause, replay, or open the tutorial in a new tab while you work. Follow the lesson requirements when the video uses a different example.
Lesson Interactive
Configure the First Extrusion
Turn the closed profile into the first solid body by choosing the correct distance, direction, and operation.
Extrusion Preview
Create a 12 mm positive extrusion as a new body.
Your Task
Turn a Closed Sketch into a Solid
Use an extrusion to create the first solid body while keeping the source sketch and feature history understandable.
- Confirm the profile is closed and selected correctly.
- Choose the correct extrusion direction and distance.
- Create a new solid body.
- Inspect the body from multiple views and rename the feature if required.
Quality check: The solid has the intended footprint and thickness, with no unintended extra bodies or open profiles.
What You Will Submit
Extruded Part
Submission standard: The solid has the intended footprint and thickness, with no unintended extra bodies or open profiles.
