This mode shows a small dialog window that you can use to create a curve from a linedef or multiple linedefs. The linedefs will be split in a number of smaller linedefs that make up the curve. Although this mode shows a dialog window, you can still use the main interface and zoom/move your view around the map.
The curve linedefs editing mode is one of the classic (2D) editing modes. This mode is volatile, which means that this mode returns to the previous stable mode when the map is saved or closed, either accepting or discarding your preview changes. You can access this mode through the Linedefs Mode.
| Enter | Accept and apply the changes, and return to the previous mode. |
| Escape | Discard the changes and return to the previous mode. |
| Ctrl + Mousewheel | Increase/decrease the number of dividing vertices. |
| LMB + Drag | Change the distance of the curve (when Fixed Circular Curve is not set). |
| RMB + Drag | Change the angle of the curve. |
| Ctrl + Alt + RMB + Drag | When Fixed Circlar Curve is set, increase/decrease the dividing vertices together with the angle of the curve to maintain a consistent circular curve |
