Draw half section view…for the following two parts (b) Make a one- view half section drawing of the step pulley. Add a partial view to show the hole and key detail. Units are in mm

The Correct Answer and Explanation is:
The drawing you’ve provided appears to be related to mechanical drafting and design, specifically requiring the creation of a half-section view for the two parts shown. To help you with this, here’s how to approach the task:
Step-by-Step Process for Drawing a Half Section:
- Understand the Part’s Geometry:
- The first part is a detailed 3D view showing a complex part with some internal details. Focus on understanding the cut section and the internal features that need to be visible in the half section view.
- The second part is the step pulley, where we are required to show both a half section and a partial view to detail the hole and key.
- Prepare the Layout for Half Section:
- Half Section: To create a half-section drawing, first draw the entire part in full detail. Then, “cut” the part in half along the centerline. The cut section should show the internal features that are exposed by the cut, while the other half remains as a view of the exterior.
- For the step pulley, you will show a section through the middle of the part, exposing the internal cylindrical surface and features.
- Draw the Section and Highlight Details:
- Half Section for the First Part: In the first part’s half section, you’ll need to focus on cutting through the middle, ensuring that you expose the internal features such as the hole, key, or any other significant detail. The side that is cut should have hatch marks to indicate the material.
- For the Step Pulley: In the second part, make sure to add a partial view of the hole and key detail. For clarity, this could be a zoomed-in area to show these details more closely.
- Add Dimensions:
- Be sure to add appropriate dimensions in mm for each feature (diameter of holes, thicknesses, lengths, etc.). You will likely need to include both the overall dimensions and the dimensions of the hole/key features as indicated in the drawing notes.
- Final Checks:
- Make sure the drawing includes a section view mark to indicate where the section is taken.
- Ensure the hatch lines are clear and follow the standard conventions (typically diagonal or parallel lines for sections).
Since you’re working with step pulleys and mechanical components, it’s important to correctly represent the geometry and ensure accuracy with the dimensions. Would you like help with a specific part of the drawing process?
