Modifies a curve or surface edge so all its points lie on the same plane.
Often used to prepare curves for use as profile curves, or for the Set Planar tool.
Best – Calculate the plane that best fits the existing curve (the plane that forces the least modification to the curve).
Axis – Flatten the curve onto an axis plane (XY, YZ, or XZ).
User Defined Plane – Flatten the curve onto an existing construction plane.
The following option appears when the Default Projection Plane is Best.
Do not move the endpoints while flattening. Locking ends allows you to maintain existing intersections.
The following options appear when the Default Projection Plane is Axis.
