Part III: Modeling Basics

Mirror
You can use the Mirror button to mirror a spline object horizontally, vertically, or along both axes. To use
this feature, select a spline object to mirror and then locate the Mirror button. To the right of the Mirror
button are three smaller buttons, each of which indicates a direction—Mirror Horizontally, Mirror
Vertically, and Mirror Both—shown in Table 12.4. Select a direction, and then click the Mirror button. If
the Copy option is selected, a new spline is created and mirrored. The About Pivot option causes the mir-
roring to be completed about the pivot point axes.

Figure 12.32 shows a little critter that has been mirrored horizontally, vertically, and both. The right image
was horizontally mirrored with the About Pivot option disabled. Notice that the eye spline was mirrored
about its own pivot.

FIGURE 12.32
Mirroring a shape is as simple as selecting a direction and clicking the Mirror button.

Trim and Extend
The Trim button cuts off any extending portion between two overlapping splines. The splines must be part
of the same object. To use the Trim feature, select the spline that you want to keep, click the Trim button,
and then click the segment to trim. The spline you click is trimmed back to the nearest intersecting point of
the selected object. This button works only in Spline subobject mode. The trimming command is depen-
dent on the viewport that is active. When the Perspective or a Camera view is active, this command uses the
Top viewport to trim.
Figure 12.33 shows a circle intersected by two ellipse shapes. The Trim button was used to cut the center
sections of the ellipse shapes away.
The Extend button works in the reverse manner compared to the Trim button. The Extend button length-
ens the end of a spline until it encounters an intersection. (There must be a spline segment to intersect.) To
