Parameters dialog box

Displays and defines the parameters in a model. You can rename, change values, or add comments to existing parameters. You can also define user parameters for use in the part.

Access:

On the ribbon, click Manage tab Parameters panel Parameters . In the Parameters table, click the Tab key to move through the cells.

Column Header Context Menu

Sort Ascending	Adds the column to the sorting set. Uses the column values to sort the parameters in an ascending order.
Sort Descending	Adds the column to the sorting set. Uses the column values to sort the parameters in a descending order.
Runtime Column Customization	Displays the Customization dialog box where you can add or remove columns.
Best Fit	Resizes the selected column to fit all contents of the column cells.
Best Fit (all columns)	Resizes all columns to fit all contents of the cells.
Clear Sort	Clears the sorting set. The parameters are left in the last sorted state.

Model Parameters

Displays the names and values of the parameters automatically created during the modeling process. This tree is not displayed for drawing documents. Each time you add a dimension or feature to the model, parameters are assigned. You can define your own parameter names in the edit boxes (see the Edit box reference). To make a parameter a multi-value parameter, right-click on any field in the row and select Make Multi-Value.
Parameter Name	The name of the parameter. To change the default name of a parameter to a descriptive name, click in the box and enter the new name. When you update the model, all dependent parameters update to reflect the new name.
Unit/Type	For a numeric parameter, the units of measurement for the parameter. For a text or true/false parameter, the data type of the parameter.
Equation	The equation that generates the value of the parameter. If the parameter is a discrete value, the value is displayed, rounded to match the precision setting for the model. To change the equation, click the existing equation and enter the new equation.
Nominal Value	The value of the equation (displayed in full precision).
Tolerance	Shows current evaluated size setting for the parameter. Click a cell to select Upper, Nominal, or Lower.
Model Value	Shows actual calculated size of the parameter.
Key	Identifies whether the parameter is a Key parameter. Select the check box to designate the parameter as a Key parameter.
Export parameter	Adds the parameter to the custom properties for the model. Custom properties can be added to parts lists and bills of materials. Select the check box to add the parameter to custom properties. Clear the check box to remove the parameter from custom properties. After adding the parameter, other documents are able to link to or derive the parameter.
Comment	The comment, if any, about the parameter. To add a comment, click in the box and enter the comment. Linked parameters include this comment.

User Parameters

Displays parameters that you define to drive dimensions and features in the model, including text and true/false parameters. To make a parameter a multi-value parameter, right-click on any field in the row and select Make Multi-Value. For more information about unit types, allowable abbreviations, and equations, click to see the Edit box reference.
Parameter Name	The name of the parameter. Click in the box and enter the name.
Unit/Type	For a numeric parameter, the units of measurement for the parameter. For a text or true/false parameter, the data type of the parameter. Click in the box to open the Unit Type dialog box. Click in the tree to select the desired units, or enter the units in Unit Specification in the box. Click OK.
Equation	The equation that generates the value of the parameter. Click in the box and enter the equation or value for the parameter.
Tolerance	Shows current evaluated size setting for the parameter. Click a cell to select Upper, Nominal, or Lower.
Model Value	The calculated value of the equation (displayed in full precision). This column is not displayed for drawing documents.
Key	Identifies whether the parameter is a Key parameter. Select the check box to designate the parameter as a Key parameter.
Export parameter	Adds the parameter to the custom properties for the model. This column is not displayed for drawing documents. Custom properties can be added to parts lists and bills of material. Select the check box to add the parameter to custom properties; clear the check box to remove the parameter from custom properties. After adding the parameter, other documents are able to link to or derive the parameter.
Comment	The comment, if any, about the parameter. To add a comment, click in the box and enter the comment. Linked parameters include this comment.

Linked parameters

Displays the names and values of the parameters exported from a part to a derived part.
Parameter Name	The name of the parameter. If multiple exported parameters have the same name, they are incremented to create a unique name for each. To change the default name of a parameter to a descriptive name, click in the box and enter the new name. When you update the base model, all dependent parameters update to reflect the new name.
Units	The units of measurement for the parameter.
Equation	The equation that generates the value of the parameter. If the parameter is a discrete value, the value is displayed, rounded to match the precision setting for the model. To change the equation, click the existing equation and enter the new equation.
Nominal Value	The ideal value of the equation (displayed in full precision).
Tolerance	Shows current evaluated size setting for the parameter. Click a cell to select Upper, Nominal, or Lower.
Model Value	Shows actual calculated value of the parameter.
Key	Identifies whether the parameter is a Key parameter. Select the check box to designate the parameter as a Key parameter.
Export parameter	Adds the parameter to the custom properties for the model. Custom properties can be added to parts lists and bills of materials. Select the check box to add the parameter to custom properties. Clear the check box to remove the parameter from custom properties. After adding the parameter, other documents are able to link to or derive the parameter.
Comment	The comment, if any, about the parameter. To add a comment, click in the box and enter the comment. Linked parameters include this comment.

Filter

This drop-down list allows you to restrict the parameters displayed in the dialog box.

• All displays all parameters with no filtering.
• Key displays only Key parameters.
• Non-Key displays only non-Key parameters.
• Renamed displays only parameters that have been renamed.
• Equation displays only parameters defined by equations or used in defining equations.

Add

Adds a new row to the table of User Parameters so that you can define a parameter. Select the parameter type from the drop-down list:

• Add Numeric
• Add Text
• Add True/False

Update

Incorporates any parameter changes that are held in memory from the current editing session.

Immediate Update

Updates the model immediately when a parameter is changed.

Link

Displays the Open dialog box so that you can locate and specify an external spreadsheet that defines parameters. Not available for drawing documents.

Click Open to add a link to the spreadsheet file. Be sure to specify Link or Embed and the data Start Cell before you open the file.

When you link to a spreadsheet, a table showing parameters in the spreadsheet is displayed in the Parameters dialog box. You cannot change the spreadsheet from the Parameters dialog box. Open the file in Microsoft Excel to make changes.

In addition to Excel files, any part file can link to another part file. It enables parameter sharing from one part file to another.

To alter which parameters are linked using the Link Parameters dialog box, right-click the parameter folder title of an already-linked component, and select Edit Folder.

Reset Tolerance

Resets all parameters at once. Not available for drawing documents.

Click Upper, Median, Nominal, or Lower to reset the value in the Tolerance column.

<< Less, More >>

Changes the display of the Parameters dialog box to reduced mode, or to full mode if the dialog box is currently displayed in reduced mode.

In reduced mode, the following parameter columns and buttons are included:

• Parameter Name
• Equation
• Driving Rule
• Key
• Filter
• Update
• Immediate Update
