The Curve command draws spline curves.

Activate the Curve command. Set points for the curve by clicking the left mouse button. Double-click or press Enter to end the curve. The tool remains active and awaiting points for another curve.

Curve Helpers:

Use the Ctrl key to constrain the next point to be along a vertical line from the last point set. Use the Shift key to force the next point to be along a horizontal line from the last point. The first point in a new curve cannot be constrained by Ctrl or Shift.)

Use the Esc key to erase the previous point in the curve currently being created.

Use Gravity to snap to the existing point in the vector data that is closest to the cursor’s position. Gravity may be activated in two ways – press the Period (.) key, or right-click to activate the Context menu and choose Gravity. If selected from the context menu, right-click will continue to function as Gravity until a new tool is selected.

When ending a curve with the Enter key, the curve ends at the last point that you set with Gravity or with a left-click, and not necessarily at the cursor’s current location. When ending a curve with a double-click, the curve ends at the location of the double-click.

You may create sharp corners in a curve by setting two consecutive points in the same location. This is most easily done by setting a point using left-click, then snapping to the same point using Gravity. (Note: For compatibility with other vector-based programs, any curve with such breaks will be exported as separate curves, divided at the sharp corners).

To close a curve, Gravity to the beginning point. The curve will automatically smooth out at the point of closure.

If you want to make a sharp point at the beginning of a closed curve, set two identical points at the curve’s beginning. This will prevent the closed end from smoothing out.
