Tool function
Constructs a segment, defined by two
end points, which may be created or
defined in free space or on a defined
object. If you press Shift while creating
the segment, you limit its orientation,
relative to the x-axis or the horizontal
aspect of the screen, by 15- increments.
Constructs a ray, defined by two points
or by a point and a direction, extending
infinitely. If you press Shift while
creating the ray, you limit its orientation,
relative to the x-axis or the horizontal
aspect of the screen, by 15- increments.
Creates a tangent line.
Constructs a vector with magnitude and
direction defined by two points. If you
press Shift while creating the vector, you
limit its orientation, relative to the x-axis
or the horizontal aspect of the screen, by
15- increments.
Tool function
Displays the distance between two
selected points or the length of a
segment, perimeter, circumference, or
radius.
Displays the area of a selected polygon
or circle.
Displays the slope of a selected line or
segment. A vertical slope is represented
by %.
Displays the measure of an angle or an
angle defined by three selected points.
