Evaluate > Surface Evaluate

Creates curves-on-surface from a single-plane cross-section.

Contour Control

Plane Origin: The 3D coordinates of the origin of the plane which intersects the surfaces to create curves-on-surface.

You can set this origin with the contour manipulator when you use the tool.
Direction Type: Select either Rotation or Vector.
Plane Normal: The vector perpendicular to the plane.

You can set this vector with the contour manipulator when you use the tool.
Vector/Plane/Point: Enter the name of a point/vector/plane to position/align the Contour manipulator with it. (You can also click a point/vector/plane to align the Contour manipulator with it. Or you can select the point/vector/plane and the surface before selecting the tool.)

Control Options

Create History: Save the history of the new curves-on-surface for later editing. If you turn Create History on, you can modify the surfaces and the curves-on-surface update.
Auto Recalc.: Update the curves-on-surface as you change the values in the Surface Evaluate window.

Buttons

Recalc: When Auto Recalc. is off, use this button to update the curves on surface to correspond to the current options.
Undo All: Undo all the changes made by the tool and return to the original surface.
Next: Finish creating curves-on-surface on the current surface and prompt for a new surface to evaluate.
