Parameter list

Displays a list of all the parameters and constraints in the drawing. They are organized in expandable categories which may include user parameters, 2D dimensional constraints, 3D dimensional constraints, 3D geometric constraints, block parameters and array parameters.

The parameter list header has columns which represent the properties of the parameters. You can arrange the parameters in ascending or descending order by clicking on a specific column head. The parameter list header has three columns by default: Name, Expression and Value. To add more columns, right click on the columns header and select the desired columns from the list.

Name
Specifies the name of the parameter.
Expression
Specifies the mathematical expression of the parameter.
Value
Specifies the value resulting from the parameter’s expression.
Type
Displays the parameter type:
  • Constraint type for constraints (Distance, Concentric etc.).
  • Parameter type for user and block parameters (Real, String).
  • Parameter type for array parameters (Real, Boolean, Enumeration).
Description
Allows to type a description for the user parameters.

Right-click menus offer additional tools for some parameters and constraints:

Units
Sets the dimension of the parameter. You can choose between none, linear, square and cubic.
Geometry-driven
If ticked, it makes the parameter geometry-driven.
Create design table
Creates a design table to drive parametric block parameters.
Animate
Animates parameter value within some range.
Exposed
Defines whether the parameter is visible and can be modified when the component is inserted into an assembly
Clean unused variables
Erases the unused variables.
Link to parameter
Links subcomponent parameter to the main level parameter.

New user parameter

Inserts a new user parameter with default values for the Expression and Value.

Delete a user parameter

Removes selected parameter and constraints from the drawing.

Show dependent parameters

Toggles the display of dependent parameters on or off.

Show defining parameters

Toggles the display of defining parameters on or off.

Hide geometrical constraints

Toggles the display of geometrical constraints on or off.

Search

Filters the parameter list to display only the parameter names that match the character string you enter.
