**Educational Website Content: Understanding 3D Rotation with Isometric Sketches**

Welcome to this interactive guide on visualizing 3D rotations using isometric sketches! Below, we explore the rotational transformations of a cube-based structure in a coordinate system. Each figure demonstrates a different rotational axis and degree of rotation.

### Task Instructions

**Objective:** Rotate the objects shown below by the indicated amount and sketch the result in the space provided. The coordinate axes do not need to be included in your sketch.

### Diagrams and Rotations Explained

1. **Figure 1:** 
   - **Rotation:** -Z 
   - **Description:** The object is rotated negatively about the Z-axis (clockwise when viewed from above). The structure is a cube assembly with three tiers.

2. **Figure 2:**
   - **Rotation:** +Y 
   - **Description:** The object is rotated positively about the Y-axis (clockwise when viewed from the front). The structure is symmetrical along the Z-axis, with a tiered, stepped arrangement.

3. **Figure 3:** 
   - **Rotation:** -X 
   - **Description:** The object is rotated negatively about the X-axis (clockwise when viewed from the side). The assembly presents a blocky Y-Z profile with varying heights.

4. **Figure 4:**
   - **Rotation:** -X again
   - **Description:** Similar to Figure 3, this view rotates the object negatively about the X-axis. It is essential to note the structural consistency in perspective shifts.

**Understanding Isometric Views:** Isometric drawings allow for a three-dimensional structure to be represented on a two-dimensional plane. It helps in visualizing how objects interact with rotational movements along different axes.

---

**Conclusion:** Practice these rotations by sketching on isometric paper grids. This exercise will enhance your spatial understanding and proficiency in representing 3D figures across different orientations.
