The geometry is not fully constrained, however. Using grips, you can still change
the radius of the arc, the diameter of the circle, the length of the horizontal
line, and the length of the vertical lines. To specify these distances, you need
to apply dimensional constraints.
NOTE Constraints can be added to segments within a polyline as if they were
separate objects.

Apply or Remove Geometric Constraints
Geometric constraints associate geometric objects together, or specify a fixed
location or angle.
NOTE This topic has been included for AutoCAD-compatibility purposes only. In
AutoCAD LT, parametric drawing technology is limited to displaying and hiding
constraints, editing constrained geometry, and changing values at the Command
prompt.
For example, you can specify that a line should always be perpendicular to
another one, that an arc and a circle should always remain concentric, or that
a line should always be tangent to an arc.
When you apply a constraint, two things occur:
The object that you select adjusts automatically to conform to the specified
constraint
