Rotation
📸 [Placeholder: Curved foundation road or circular arrangement]
Rotation Transform creates arcs, curves, and circular arrangements by rotating each item in your grid by a set angle.
Rotation adds an angular offset that accumulates across your X axis:
- 15° rotation → Each item rotates 15° more than the previous
- Negative rotation → Curves in the opposite direction
| Action | Default Key | Description |
|---|---|---|
| Activate Rotation |
, (Comma, hold) |
Enable rotation mode |
| Increase Rotation |
Scroll Up or NumPad 8 (while holding ,) |
More rotation per item |
| Decrease Rotation |
Scroll Down or NumPad 5 (while holding ,) |
Less rotation per item |
- Positive rotation — Curves right (clockwise from above)
- Negative rotation — Curves left (counter-clockwise)
- Multi-row grids — Creates parallel curved lanes (like road lanes)
When rotation is active, the HUD shows detailed information:
Rotation [Z]*: 15.0° (R=12.5m, 24/circle)
- Rotation [Z] — The rotation axis (currently Z only)
- 15.0° — Degrees of rotation per item
- R=12.5m — Calculated radius of the curve
- 24/circle — How many items to complete a full 360° circle
The asterisk (*) and yellow highlight indicate the mode is active.
- Select a foundation hologram
- Scale to 12×1 (NumPad 8 eleven times)
- Hold
,(comma) to enter rotation mode - Scroll to set 15° rotation
- Release
,and place
You now have a curved arc of 12 foundations!

- Select a foundation hologram
- Scale to 12×3 (12 wide, 3 deep)
- Hold
,and set 15° rotation - Place — three parallel curved lanes!

| Use Case | Suggested Rotation |
|---|---|
| Gentle curve | 5° - 10° |
| Standard curve | 15° - 20° |
| Tight curve | 30° - 45° |
| Full circle (24 items) | 15° |
| Full circle (12 items) | 30° |
- Start with 15° — Good default for most curves
- Use the HUD — Check "buildings per circle" for planning
- Combine with Y scaling — Create parallel lanes
- Test small first — Curves can be tricky to visualize
- Use Smart! Panel — Press K to type exact rotation values
