For this command to be successful you must have at least one other extrude effect applied to an object and in view. After the vanishing point has been copied the property bar indicates the object s vanishing point as VP Locked To Page. Sharing vanishing points Choosing Shared Vanishing Point enables you to have multiple objects share the same vanishing point but you must have applied at least an initial extrude effect to your objects before using this command. Immediately after you choose this option your cursor changes to a vanishing point targeting cursor which signifies that you now target any other extruded object for the purpose of creating a common vanishing point position for multiple objects. This creates a similar effect to copying vanishing points but the overall effect is that every object on the page is in the same scene. The objects are positioned in different areas but it s one big visually integrated scene. Shared Vanishing Point can be repeated for as many objects as you like. When multiple objects share a vanishing point they can be repositioned anywhere on your document page and the perspective on the 3D object updates to maintain the relationship of a common vanishing point. Figure 19-5 shows the results of setting up a shared vanishing point arrangement with four objects. The figure has been retouched you can t view more than one vanishing point at a time to show the converging point for all the objects sides their depth aspect. Setting a relative position for vanishing points The Page or Object vanishing point option in the property bar is used to toggle the measurement state of object vanishing points between page and object. While the option is inactive meaning the button is not depressed the vanishing point position boxes enable you to specify the vanishing point relative to your page origin a value determined either by the lower-left corner by default or by .
