User variables have the following characteristics:
■ Default values are: Name = user1, Expression = 1, and value = 1.00.
■ Name should be alphanumeric and cannot begin with a number, contain
spaces, or exceed 256 characters.
■ Expression values should be within the range of -1e100 and 1e100.
Edit a Dimensional Variable
You can edit the dimensional variable name and expression. To do so:
■ Double-click the name or expression box.
■ Select the row and press F2. Press the Tab key to edit the contiguous
columns.
You cannot edit the Value column.
When you rename a dimensional variable, all instances of the variable are
updated in the drawing and in the Parameters Manager palette.
TIP Use the shortcut menu for the Name and Expression cells when copying and
pasting values. The Expressions shortcut menu contains commonly used
mathematical functions.
Invalid expressions are displayed in red text.
Delete a Dimensional Variable
When you delete a dimension variable:
■ The associated dimensional constraint in the drawing is removed.
■ The variables retain the value calculated by the expression as a constant.
This action is for variables referenced by other variables, and ensures that
the geometry does not change.
Sorting a Column
Click a column heading to sort the variables in the table in ascending or
descending order of the column property. When you sort by variable type,
the name column is second in order to be sorted.The sort order is persistent.
The sort order is not affected when you add a variable, or change a name or
expression.
Defining a Parameter Group
The Parameters Manager allows you to define parameter groups in the drawing
editor. A parameter group is a collection of named parameters. It contains a
