About the Modify Analytic Surface Feature
Use the modify analytic surface feature to edit the base dimensions that drive the analytic surface. You can modify the following dimensions of a cylinder, a torus, or a cone.
• Cylinder—Radius; the axis remains fixed.
• Torus—Radius of the circle and radius from the center of the circle to the axis of revolution. The axis of revolution remains fixed.
• Cone—Angle; the axis and vertex of the cone remain fixed.
