390), but the value displayed is based on the formatting of the units (for
example, 30 if decimal degrees).
When an expression with variables evaluates to greater than 360 or less than
-360, the constraint value is displayed in the Parameters Manager based on
the units of the drawing.
The following table outlines the valid constraint objects and points:
CharacteristicsValid Objects or Points
Pair of lines
 When two lines are selected, the angle
between the lines is constrained. The
Pair of polyline segment
initial value always defaults to a value
less than 180 degrees.
Three constraint points
Arc
 When three constraint points are spe-
cified, the following applies:
 First point — angle vertex
 Second and third points — end-
points of the angle
 When an arc is selected, a three-point
angular constraint is created. The angle
vertex is at the center of the arc and
the angle endpoints of the arc are at
the endpoints of the arc.
List of Prompts
The following prompts are displayed.
Select first
line (page 260) or arc (page 261) or [3Point (page
261)] <3Point>: Pick a line, or an arc, or three points to be constrained
Line
Selects a line object.
First Line Specifies the first line to be constrained.
Second Line Specifies the second line to be constrained.
Dimension Line Location Determines where the dimension line is located
on the constrained object.
