After you've applied a vector extrusion to an object, you can select the various components and edit them. You can also edit a vector extrusion by shaping the control object, changing the depth of the extruded surfaces, and by the rotating the vector extrusion. You can also change the vector extrusion type, as well as move, lock, copy, and share an extrusion's vanishing point. You may also want to control the facet size used when CorelDRAW renders and prints illustrations containing extrusions.
Extruded surfaces form a dynamically linked group with the original object (also called the control object). When you change the shape of the control object, the extruded surfaces automatically reflect these changes. For example, if you extrude a polygon, and use the Shape tool to make the polygon a star, the extruded surfaces change to reflect the control object's new shape.
By changing the vector extrusion type, you determine the position of the extruded surfaces relative to the control object, as well as the position of the vanishing point.
You can move a vector extrusion's vanishing point without changing the extrusion type. You can also lock a vanishing point to the page or to the control object. When you lock the vanishing point to the page, it remains fixed in its position relative to the page. When you move the control object, the vanishing point maintains its position. The vector extrusion is redrawn based on the control object's new position.
Further, you can copy and share vanishing points. When you copy a vector extrusion's vanishing point to another object, a new vanishing point is created on top of the existing vanishing point. As a result, both objects appear to recede toward the same point. The two vanishing points can be edited independently. When you share a vanishing point, the vector extrusions all use one vanishing point. Changes to the vanishing point's position affect all the extrusions that share that point.
Facet size represents the minimum size of the polygonal surfaces used to create the extrusions. Each facet consists of a unique color, therefore, smaller facets create smoother color transitions and larger facets create blockier color transitions on lighted extrusions.
When you're editing your drawing, you may want to separate the various extruded surfaces or decide to clear them completely.
