Control Geometry with the Parameters Manager
The Parameters Manager lists dimensional constraint parameters, reference
parameters, and user variables, which you can also create, edit, and organize.
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 in the Parameters
Manager.
You can easily create, modify, and delete parameters from the Parameters
Manager.
The Parameters Manager supports the following operations:
Click the name of a dimensional constraint parameter to highlight the
constraint in the drawing.
Double-click a name or expression to edit it.
Right-click and click Delete to remove a dimensional constraint parameter
or user variable.
Click a column heading to sort the list of parameters by name, expression,
or value.
Use Operators in Expressions
Dimensional constraint parameters and user variables support the following
operators within expressions:
DescriptionOperator
Addition+
Subtraction or unary negation-
Floating point modulo%
Multiplication*
Division/
Exponentiation^
Parenthesis, expression delimiter( )
