Learning Targets
- Identify when motion or interference checks are needed.
- Use CAD checks to locate collisions or blocked movement.
- Record evidence that supports a design decision.
IED Unit 3 • Lesson 3.9
Assembly Motion and Functional Checks
Focus question: How do motion checks reveal interference or alignment issues?
Mission Briefing
Today’s Plan
Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Run Functional and Motion Checks.
Success Looks Like
You can use motion or interference checks to find problems before printing.

Opening Prompt
How do motion checks reveal interference or alignment issues?
Connect your response to the decision, evidence, or quality standard required for Run Functional and Motion Checks.
Reveal: useful engineering move
This lesson is ready to move forward when the evidence meets this standard: The check covers the intended range and documents both successful behavior and any interference.
Core Skill
What We Are Practicing
Motion checks reveal issues that static views may hide.
Interference is a design problem, not just a display problem.
Functional checks should happen before fabrication.
Your Task
Run Functional and Motion Checks
Use available joint motion and visual inspection to identify interference, overtravel, or misalignment in the assembly.
- Identify the joint or relationship that can be tested.
- Move the component through its intended range.
- Watch for collisions, separation, or unexpected rotation.
- Record the result and any needed correction.
Quality check: The check covers the intended range and documents both successful behavior and any interference.
Lesson Interactive
Find the Interference-Free Motion Limit
Move the payload tray through its travel and identify the largest position that does not contact the body wall.
Motion Sweep

Status
Motion Controls
Find the maximum clear travel and choose a design response that prevents interference.
What You Will Submit
Motion Check Record
Submission standard: The check covers the intended range and documents both successful behavior and any interference.
