  5. Optionally press Backspace before finishing the input to delete the last knot point.
  6. Right-click or press Esc to finish the input.
  7. The B-spline is created, including a set of internal geometry (weight circles and knot points).

    1. Optionally keep creating B-splines.
    2. To finish, right-click or press Esc, or start another geometry or constraint creation tool.
