Circular Plate Problem No.2 - Projection of Planes - Engineering Drawing

## TL;DR

A circular plate with a 60mm diameter resting on a point is inclined at 30 degrees to hp. Three views need to be drawn.

## Key Insights

• 🫵 The circular plate is initially drawn as a circle in the top view and as a line in the front view.
• 🫥 The inclination of the circular plate is represented as a line in the side view.
• 🫵 The side view of the circular plate is projected from the top view using points and angles.
• 💠 The true shape of the circular plate is only visible when the plane is horizontal and observed from the top. In inclined positions, the shape appears as an ellipse.
• 🫵 Proper notations and dimensions are essential in accurately representing the circular plate in the three views.
• 🫵 The first angle method of projection is used to draw the side view of the circular plate.

### Q: How is the circular plate initially drawn in the top view?

The circular plate is drawn as a circle, with a diameter of 60mm, divided into eight equal parts.

### Q: How does the circular plate appear in the front view?

In the front view, the circular plate appears as a line, with points labeled from one to eight.

### Q: How is the inclination of the circular plate represented in the side view?

The circular plate's inclination is represented by drawing a line at a 30-degree angle and projecting points from the top view onto it.

### Q: How is the side view of the circular plate represented?

Points from the top view are projected upwards onto a line at a 45-degree angle, creating a side view of the circular plate.

## Summary & Key Takeaways

• A circular plate with a 60mm diameter is resting on a point and inclined at 30 degrees to hp.

• The circular plate appears as a line in the front view.

• In the top view, the plate is drawn as a circle, while in the side view, it appears as an ellipse.
