Key:

Prioritize Hands-On Practice:
- Use CAD tools (L4) for orthographic/pictorial drawings.
- Reinforce line division (L3) with scale models.
Common Pitfalls:
- Students often confuse 1st vs. 3rd angle projection (L2→L3).
- Loci construction (L4) requires iterative practice.
Engagement Ideas:
- Competitive sketching drills for symbols/lines.
- Real-world case studies (e.g., bridge forces for L4).
