Preset Views Explained
| View | Key | Purpose | Technical Detail |
|---|---|---|---|
| Front | 1 | Primary elevation | Negative Z-axis |
| Left | 3 | Side profile | Positive X-axis |
| Top | 5 | Bird's eye view | Negative Y-axis |
| Bottom | 6 | Underside inspection | Positive Y-axis |
| Right | 4 | Right profile | Negative X-axis |
| Rear | 2 | Rear elevation | Positive Z-axis |
Pro Tip: Professional CAD review typically follows Front → Right → Top view sequence.
Advanced Features
Projection Modes
