About Controlling 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.
You can easily create, modify, and delete parameters from the Parameters Manager,
which 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:
| Operator | Description |
|---|---|
| + | Addition |
|
– |
Subtraction or unary negation |
|
% |
Floating point modulo |
| * |
Multiplication |
| / | Division |
| ^ | Exponentiation |
| ( ) | Parenthesis, expression delimiter |
|
. |
Decimal separator |
unit separator rather than a subtraction operation. To specify subtraction, include
at least one space before or after the minus sign. For example, to subtract 9″ from
5′, enter 5′ -9″ rather than 5′-9″.
Understand Precedence in Expressions
Expressions are evaluated according to the following standard mathematical rules of
precedence:
- Expressions in parentheses first, starting with the innermost set
- Operators in standard order: (1) unary negation, (2) exponents, (3) multiplication
and division, and (4) addition and subtraction - Operators of equal precedence from left to right
