◦ Geometry collector—Displays the bodies or the group of curves, quilts, or facet geometry to warp.
◦ Hide Original check box—Hides the geometry of the original entity in the warp.
◦ Copy Original check box—Copies the original entity in the warp after you have completed it.
◦ Facet Preview check box—Displays a preview of the warped geometry within the feature. Facet Preview is unavailable if the selection consists only of facet geometry, curves, or both.
▪ Facet Preview slider—Increases or decreases the preview quality.
▪ Facet Preview box—Specifies a preview quality value from 0 to 100.
◦ Direction collector—Displays the coordinate system or reference plane selected for the warp.
◦ Spine collector—Sets the curve or edge that determines the spine deformation.
◦ Details button—Opens the Chain dialog box containing information about the selected curve or edge.
• List

◦ Point list—Sets behavior of selected points.
▪ Free—Points move freely.
▪ H/V (Ctrl+Alt)—Points move only in a horizontal or vertical direction.
▪ Normal (Alt)—Points move normal to a selected face or plane.
◦ Tangent list—Specifies behavior of a tangent when you drag it.

—Exports the parameter value for editing outside of Warp.
—Exports the parameter value for editing outside of Warp.• Marquee
◦ First and Second (when Rectangular is selected)
Rectangular is selected)—Exports the parameter value for editing outside of Warp.▪ Sets the Start and End of the marquee in the first and second directions normal to the spine as a percentage of the original marquee (when Marquee Size method is Proportional).
▪ Sets the Start and Length of the marquee in the first and second directions normal to the spine as a value (when Marquee Size method is Absolute).
▪ Sets the Start Offset and End Offset of the marquee in the first and second directions normal to the spine as a value offset from the marquee start or end (when Marquee Size method is Offset).
◦ Radial and Depth (when Radial is selected)
Radial is selected)—Exports the parameter value for editing outside of Warp.▪ Sets the Start and End of the marquee radial to the spine in one direction, and at a depth in the second, as a percentage of the original marquee (when Marquee Size method is Proportional).
▪ Sets the Start and Length of the marquee radial to the spine in one direction, and at a depth in the second, as a value (when Marquee Size method is Absolute).
▪ Sets the Start Offset and End Offset of the marquee radial to the spine in one direction, and at a depth in the second, as a value offset from the marquee start or end (when Marquee Size method is Offset).
◦ Radial (when Axial is selected)
Axial is selected)—Exports the parameter value for editing outside of Warp.▪ Sets the Start and End of the marquee along the spine as a percentage of the original marquee (when Marquee Size method is Proportional).
