As you can see, part of the equation for determining the area of the circle is
included in the Radius dimensional constraint parameter and part was defined
as a user variable. Alternatively, the entire expression, sqrt (Length * Width /
PI), could have been assigned to the Radius dimensional constraint parameter,
defined in a user variable, or some other combination.
Protect Expressions in Dynamic Constraints
When a dynamic dimensional constraint references one or more parameters, the
prefix fx: is added to the name of the constraint. This prefix is displayed only
in the drawing. Its purpose is to help you avoid accidentally overwriting
parameters and formulas when the dimension name format is set to Value or
Name, which suppresses the display of the parameters and formulas.
