Many objects are symmetrical - mirroring creates the other half.
To mirror an object across an axis:
| Mirror Across | Scale Value |
|---|---|
| X axis | Scale X = -1 |
| Y axis | Scale Y = -1 |
| Z axis | Scale Z = -1 |
For naturally symmetrical things:
1. Create right side
2. Position at positive X
3. Duplicate
4. Scale X to -1
5. Position at negative X (same distance)
Mirrored objects may need rotation adjustment depending on design. Always check the result!
