After you apply a circular or sweep extrusion to an object using the
expanded Extrude palette, you need to set the extrusion axis, which is
represented by a black bar. A mirror image of the selected object
shows the extrusion at 180 degrees.
To set the extrusion axis: Drag the black bar right, left, up, or
down, depending on the direction you want to extrude. The mirror
image of the object moves as you drag the axis. Press Enter or dou-
ble-click to complete the extrusion.
Extrusion options
You can use pop-up palettes of extrusion and lighting presets in the
Extrusion palette to modify extruded objects. If you expand the
Extrude palette, you can use options to control lighting and rotation
of extrusions. You can set these options before you extrude an object,
or to edit an extruded object.
Before extruding a selected object, set up the options you
want and click Apply to extrude the object.
After extruding an object, double-click it, change the set-
tings you want, and click Apply to apply the settings.
You can control the color and position of the light source to change
the shading of extruded objects. Canvas uses shades of gray to create
highlights and shadows. Canvas then mixes the highlights and shad-
ows with the color of the light source and the fill color of the object.
