To Create a Warp Feature
1. Open a model to alter the form and shape of the geometry.
2. Click Model > Editing > Warp. The Warp tab opens. The Geometry collector is active by default.
3. Select a solid, facet, a set of quilts, or a set of curves to perform the warp operations. Region selection is available in Warp. Click anywhere in the graphics window and drag to draw a bounding box around the geometry that you want to select. The geometry within the boundary box is selected.
 
* To maximize modeling flexibility and minimize the impact of changes in your Warp feature, use geometry created with intent references. Not all features implement alternative referencing. Those that do not remain in their original position and are not affected by the warp operations.
The default coordinate system appears automatically in the Direction collector on the References tab.
4. Specify one or more of the following options under References.
◦ Geometry collector—Displays the solid or the set of curves, quilts, or facets that you selected for the warp operations. You can change the selection by clicking the collector and selecting another entity using standard selection tools.
◦ Hide Original check box—Hides the geometry of the original entity selected for the warp operation.
◦ Copy Original check box—Copies the original entity selected for the warp after you have completed the warp operations on it. This option is not available for solids.
◦ Facet Preview check box—Displays a preview of the warped geometry within the feature. Facet Preview is unavailable if the selection consists only of facets, curves, or both.
◦ Facet Preview slider—Increases or decreases the facet preview quality.
◦ Facet Preview box—Specifies a preview quality value from 0 to 100.
◦ Direction—Displays the coordinate system or reference plane as a reference for the warp operations. To change the selection, click the collector and select another reference.
5. Select a warp tool on the Warp tab. Specify one or more of the available settings on the Options tab and Marquee tab for the selected warp tool, or use the graphical handles to change the geometry.
6. To maintain tighter tangency control at boundaries, right-click and choose Use Boundary Tangents.
 
* The Use Boundary Tangents command increases a model's regeneration time.
7. Click List. The warp operations performed on the selected entity are displayed in the sequence that they were performed.
8. If required, select an operation to edit from the list.
◦ Select an operation in the list and edit it.
◦ Click to select the previous operation.
◦ Click to select the next operation.
◦ Click to select the first operation in the list.
◦ Click to select the last operation in the list.
◦ Select an operation in the list and click to delete it.
◦ Select a new warp operation on the Warp tab to insert after the selected operation in the list.
