User variables have the following characteristics:
■ Default values are: Name = user1, Expression = 1, and value = 1.00.
■ Name should be alphanumeric.
■ 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.
Invalid expressions are displayed in red text.
Delete a Dimensional Variable
The following are the current behavioral changes in the drawing 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.
Filtering the Display of Variables
You can filter the display of variables to do the following:
■ Display All Parameters — Displays all associative variables. No filter is
applied.
■ Display Parameters Used in Expressions - Displays all variables that contain
expressions to evaluate a value, and variables contained in expressions.
Sorting a Column
The sort order is not affected when you change a cell value.
