Edit curve points

Edit the control points of a NURBS curve to change its path.

Before you start

Add a NURBS Curve or NURBS Circle from Add, or select an existing curve object. Select one curve at a time for point editing.

Shape a path by moving its control points while keeping the curve editable.

In Modeling, select the curve and press Tab to enter Curve Edit Mode.
Select the control points you want to change. Use G to move, R to rotate, or S to scale the selected points.
Confirm the transform and inspect the curve between the points. Press Tab to return to Object Mode.

Controls	What changes
Control points	A NURBS curve is influenced by its control points and need not pass through every one. Judge the resulting curve, not only its control polygon.
Point versus object transform	Editing selected points changes the path’s shape. Moving the object in Object Mode changes its placement as a whole.
Selection	A selects all curve points. Keep only the intended points selected when refining a local bend.

Add a curve, enter curve editing, and move one control point. Inspect how the neighboring curve changes.

Inspect bends from more than one angle and look for abrupt changes in direction. A smooth screen projection can still hide an unwanted bend in depth.

Open the editor and follow the steps with your own scene.
