Chapter 3: Working with Sketches

move (such as a collinear relation), you are prompted with a choice to delete the existing relation

and continue or copy the entity without the relation. As mentioned earlier, be careful with the icon

for this function because it looks almost identical to the Construction Geometry icon, especially as

printed here in gray scale.

Sketch Picture is a picture that is placed in the sketch, lies on the sketch plane, and is listed in the
FeatureManager indented under the sketch. The Sketch Picture may be suppressed independently
from the rest of the sketch, and when the sketch is hidden, the picture is not visible. You can easily
move, resize, and rotate Sketch Pictures, as well as apply a transparent background color to them.
Sketch Pictures are usually used for tracing over or as a planar decal without the need for
PhotoWorks. Figure 3.25 shows the controls for manipulating the Sketch Picture feature.

Equation Driven Curve is a sketch spline driven by either an explicit or parametric equation, as

shown in Figure 3.26. An explicit equation is in the form y = f(x), while a parametric equation uses

multiple equations driven by a common parameter value of the form, such as

x = cos(t)

y = sin(t)

0>t>pi

where t is a number in radians.
