Parameters Manager (Block Editor))

Parameters Manager (Block Editor))

Controls the associative parameters used in the Block Editor.

In the Block Editor, the Parameters Manager displays a consolidated view of all parameters
and user-defined properties for the block definition.

The Parameters Manager palette includes a grid control with three columns (Name, Expression,
Value) by default. You can add one or more additional columns (Type, Order, Show,
or Description) using the shortcut menu.

Column

Description

Name

Displays the variable name

Expression

Displays the real number or equation, for example, d1+d2

Value

Displays the value of the expression

Additional Columns

Type

Displays the dimensional constraint type or variable value

Order

Controls the order properties are displayed in the Properties palette

Show

Displays the parameter as a property of the block reference

Description

Displays the comments or notes associated with the user variable

The Type column affects the formatting of the parameter in the Parameters Manager
and Properties palette. It also affects the value of the parameter when the block
is scaled.

Type Units Precision Block Scale Factor
Distance LUNITS LUPREC Scaled by scale factor
Angle AUNITS AUPREC No scale
Real Decimal LUPREC No scale
Area Decimal LUPREC Multiplied by square of scale
Volume Decimal LUPREC Multiplied by cube of scale
String Not applicable Not applicable Not applicable

The Type cell for User parameters displays a drop-down list of the value types. The
parameter can be sorted and can be set to Show or Hide in the Properties palette.
The value of the parameter resets to 1 when you change the type from String to another
type.

Parameters can be renamed; equations and values can be entered or modified. Changes
to a parameter name are immediately updated throughout the table and in the Block
Editor.

The parameters for the block definition are organized in the following categories:

  • Action Parameters
  • Dimensional Constraint Parameters
  • Reference Parameters
  • User Parameters
  • Attributes

You can only add user parameters to the table. When you delete any item from the table,
the item is automatically deleted from the block definition.

Create a Dimensional Variable

To create a dimensional variable, you apply a dimensional constraint to an object
in the Block Editor. Dimensional variables are displayed under the Dimensional Constraint
Parameters group header in the Parameters Manager palette. (Not available in AutoCAD
LT)

User variables are custom variables that create and drive object relationships. These
variables can contain constants, or equations.

Click the New User Parameter icon on the Parameters Manager palette to create a user
variable. Alternatively, double-click an empty cell to create a user-defined variable.

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.

Searching a Parameter

An edit box in the upper-right corner of the Parameters Manager allows you to search
for parameters by name.

Shortcut Menu Options

The following options are displayed on the shortcut menus in the Parameters Manager
palette. (Not available in AutoCAD LT)

Column Header Shortcut Menu

Expression

Displays or hides the Expression column.

Value

Displays or hides the Value column.

Type

Displays or hides the Type column.

Show

Displays or hides the Show column. The Show property can be set for dimensional constraint
parameters and user parameters created in the Block Editor only. This property is
read-only and is set to No for dimensional constraint parameters and user parameters
which are created in the drawing editor.

Order

Displays or hides the Order column.

Description

Displays or hides the Description column.

Maximize All Columns

Displays all columns using the maximum value in each column as the base.

Row Shortcut Menu

Delete Parameter

Deletes the selected parameters from the drawing and the Parameters Manager.

Convert Parameter

Converts dimensional constraints and user parameters to constraint parameters and
user parameters.

Cell Shortcut Menu

Cut

Removes the value from the cell and pastes it to the clipboard.

Copy

Copies the value in the cell and pastes it to the clipboard.

Paste

Pastes the immediately transferred value from the clipboard.

Delete

Deletes the value from the cell based on the selection.

Expressions

Displays a list of functions for use in the expression column (available only within
the Expression cell)
