Session 5: “Advanced Sketching Techniques Continued”
Architect:
Syed Shayaan Haider - Markhor3D
Session Overview
In this session, Grade 6 students will deepen their OnShape sketching skills by learning how to use advanced tools such as text, construction lines, and the trim tool. These tools will help them add detail, create reference geometry, and clean up their sketches to form precise, closed figures. Mastering these techniques is essential for creating designs that are ready for 3D modeling and eventual extrusion.

Learning Objectives
By the end of this session, Grade 6 students will be able to:
- Use the Text Tool: Add text elements to their sketches for labels or decorative features.
- Apply Construction Lines: Create construction lines as guides to help align and structure their sketches without affecting the final geometry.
- Utilize the Trim Tool: Remove unwanted or excess parts of their sketch to achieve a clean, closed figure.
- Enhance Sketch Precision: Combine these tools to refine their sketches, ensuring they are fully defined and ready for 3D modeling.

Structure and Lesson Plan (Total Time: 60 minutes)
1. Introduction and Recap (10 minutes)
- Welcome:
- “Good morning, Grade 6! Today, we’re continuing our journey with advanced sketching in OnShape.”
- Recap Previous Session:
- “Last session, you refined your sketches using mirror, trim, and geometric constraints. Today, we’ll add more detail by using text and construction lines, and further clean up our sketches with the trim tool.”
- Session Overview:
- “We will learn how to add text to our sketches, use construction lines as guides, and remove unwanted lines with the trim tool. These techniques will help you create precise, closed sketches that are ready for 3D modeling.”
2. Adding Text to Your Sketch (15 minutes)
- Explain the Text Tool:
- “The text tool allows you to add words or numbers to your sketch. You can use it to label parts of your design or add decorative elements.”
- Demonstration:
- Step 1: “Select the text tool from the sketch toolbar.”
- Step 2: “Click on the sketch plane and type the desired text.”
- Step 3: “Adjust the size, font, and position of the text as needed.”
- Placeholder: [Google Image Search “OnShape text tool sketch”]
- Hands-On Practice:
- “Now, add a label to your sketch—perhaps your name or a simple word that describes your design. Experiment with different fonts and sizes.”
3. Using Construction Lines (15 minutes)
- Explain Construction Lines:
- “Construction lines are temporary guide lines that help you plan and align your sketch. They do not appear in the final model but are very useful for making sure everything is positioned correctly.”
- Demonstration:
- Step 1: “Select the construction line option from the sketch toolbar.”
- Step 2: “Draw a line on your sketch that will act as a guide. For example, draw a line to mark the center of your design or to align edges.”

- Hands-On Practice:
- “Add construction lines to your sketch to help you align other elements. Use these guides to ensure that your shapes are symmetric and well-spaced.”
4. Refining Your Sketch with the Trim Tool (15 minutes)
- Explain the Trim Tool:
- “The trim tool lets you remove unwanted parts of your sketch. This helps clean up your drawing and ensures that your sketch is a closed figure.”
- Demonstration:
- Step 1: “Select the trim tool from the sketch toolbar.”
- Step 2: “Click on the lines or parts of your sketch that you want to remove.”
- Step 3: “Watch as the tool removes the excess, leaving you with a clean, closed shape.”
- Placeholder: [Google Image Search “OnShape trim tool”]
- Hands-On Practice:
- “Use the trim tool to clean up your sketch. Remove any overlapping or extra lines so that your design forms a perfect closed figure, ready for extrusion later.”
5. Sharing and Feedback (5 minutes)
- Student Sharing:
- “Would anyone like to share their refined sketch? Explain how you used text, construction lines, and the trim tool to improve your design.”
- Peer Feedback:
- “Listen to your classmates and give one positive comment or a suggestion for improvement.”
- Teacher Feedback:
- “Great work! I can see that adding construction lines really helped you align your design, and the text adds a nice personalized touch.”
6. Conclusion and Next Steps (5 minutes)
- Summarize the Session:
- “Today, you learned how to enhance your sketches in OnShape using advanced tools like text, construction lines, and the trim tool. These tools help make your designs precise and ready for the next step—extrusion into 3D models.”
- Preview Next Session:
- “In our next session, we’ll focus on extruding these refined sketches to create full 3D models. Your improved sketches today will be the foundation for those 3D designs.”
- Closing Encouragement:
- “Excellent work today! Keep practicing these tools, and remember that every detail in your sketch makes a big difference in your final 3D model.”
Glossary
- Text Tool: A tool used to add words or numbers to a sketch, which can be used for labeling or decoration.
- Construction Lines: Temporary guide lines used to align and organize elements in a sketch. They do not appear in the final model.
- Trim Tool: A tool used to remove unwanted parts of a sketch, helping to create a clean, closed figure.
- Closed Sketch: A 2D drawing where all lines connect to form a complete boundary, essential for extrusion.
- Extrusion: The process of adding depth to a 2D sketch to create a 3D model.
- Precision: Being exact and accurate in measurements and design.
