The Variant Management dialog.

SUMMARY

This dialog enables you to add and configure variants of the main PCB board design. Variants are variations of the main PCB board design and using variants, any number of variations of the base design can be designed. Each component in the base design can be configured to be:

Fitted - the default setting when a new variant is created.
Not Fitted - the original component as used in the base design is not fitted/used in this variant of that design.
Fitted with modified component parameters, such as the component's value.
Alternate Part - completely replacing one component, with another.

Variants that use any of these types of variations are all referred to as Assembly Variants, as they only impact on the assembly process. All variants share the same fabricated base board.

ACCESS

The Variant Management dialog can be accessed in the following ways:

Click Project | Project Actions » from the main menu of any document in the project.
In the Projects panel, right-click on project name and select Variants.
In the Schematic Editor, right-click a placed component and select Part Actions » Variants.

OPTIONS/CONTROLS

The dialog is divided into two main regions:

The upper region, titled Components, lists all of the components in the base design.
The lower region, titled Component Parameters, details all of the parameter variations of the component(s) currently selected in the upper region.

Components

Project Components - This region of the dialog lists each component in the project. For each component, the Hierarchy Path and Logical designator are listed, as well as Comment and physical Designator. The Document and Original Library Link list where source documents are located.

Double-click on a component to jump to that component on the schematic.

Component Variation - After a new variant is added, a dedicated column appears to the right of Project Components. The name given the new variant appears as the title and the Component Variation column lists any variations for each component.

Once the variant has been created, you can configure the state of each component. This is done by clicking the component cell in the new column to reveal the button, or by right-clicking to access the context menu commands. When the button is clicked, the Edit Component Variation dialog will open, presenting three choices:

Fitted - the original component as used in the base design is also fitted/used in this variant of that design. For a newly added variant, all components are Fitted by default and the cell is empty. Note that individual parameters can also be varied for a Fitted component - simply type in the new parameter value. Varied parameters are shown in bold.
Not Fitted - the original component as used in the base design is not fitted/used in this variant of that design. For a Not Fitted component, the cell displays the text Not Fitted.
Alternate Part - this option gives access to selecting the alternate part. Once chosen, the cell displays the alternate part's Library Link. The lower region of the dialog will display all of the parameters in the alternate part.

To make a variant active, either click on that variant's name in the column header, or click in any of that variant's cells.

When you configure variations in the Variant Management dialog, the settings are saved in the project file. This includes the Not Fitted state, local parameter variations to a Fitted component, and the parameter values of Alternate Parts. The Alternate Parts are stored in the file <ProjectName>.PrjPcbVariants.

To change the order the variants are listed, click and hold on the column heading, then drag that column to a new location. Use this in combination with the Fit to Width checkbox to position and size the variant of interest in your preferred working location.

Right-click Commands

The following commands are available on the region's right-click menu:

Columns - click to see/hide columns that are not needed. Toggle the visibility of any column.
Edit Selected - make changes to the selected component.

Edit Selected is only available when right-click is done in Component Variation column.

Set Selected As - click to change to Fitted, Not Fitted, or Alternate.
Only Show Varied Components - click to show varied components.
Filter - click to filter components by Show Fitted with Varied Parameters, Show Not Fitted, or Show Alternate.

Filter is only available when Only Show Varied Components is checked.

If you have been experimenting with the Filter options and have applied different filters, you may need to reset the filter before attempting another update. To do this, disable the Only Show Varied Components option to clear the filter system, then re-apply it and clear the Filter options as required.

Report - click to open the Report Preview dialog to create a printout of the Components region.
Save All - click to open the Save Grid Contents to File dialog to save all project components to another location.
Save Selected - click to open the Save Grid Contents to File dialog to save all selected project components to another location.
Select All - click to select all cells.
Select Column - click to select the current column.
Invert Selection - click to select all components other than those that are currently selected.
Cross Probe - click to show, on the schematic, the selected component's location.

Standard Windows multi-select techniques are supported; use these to select and configure multiple components simultaneously.

Component Parameters

For each component, you can have Parameter Variations. The Parameter Name and Original Value are listed. To the right of Parameter Variations is the newly-added variant column where the New Value is listed. The New Value that appears is a copy of the base design component value until you make a change. Right-click to access different menu items from the pop up menu. From the pop up menu, you can:

Edit Selected - click to change New Value of selected variant.
Reset Selected - click to restore New Value back to original value.
Reset All - click to restore all New Value cells to original value, regardless of current selection.

Edit Selected, Reset Selected, and Reset All are only available when right-click is done in the newly-added variant column.

Update Values From Library - click to bring any parameter changes made to a library component that is used as an Alternate Part into the variant definitions. Note that this updates the parameters only.
Only Show Varied Values - click to show only varied values.
Cut - click to delete cell contents. A Confirm window opens for confirmation before deletion occurs.

Cut is only available when right-click is done in Component Variation column.

Report - click to open the Report Preview dialog to create a printout of the Component Parameters region.
Save All - click to open the Save Grid Contents to File dialog to save all parameters to a .txt file in another location.
Save Selected - click to open the Save Grid Contents to File dialog to save all selected parameters to a .txt file in another location.
Select All - click to select all cells.
Select Column - click to select the current column.
Invert Selection - click to select all parameters other than those that are currently selected.

Additional Controls

Add Variant - click to create a new variant of the base design. The Edit Project Variant dialog will open. Use this dialog to add, edit or remove a variant, and specify any required variant-level parametric data. This button includes a dropdown that is used to access the Clone Selected Variant command. Cloning is used when you need to define a number of variants that are very similar.
Delete Variant - click to delete selected Variant(s). A Confirm Delete Variant window opens for confirmation before deletion occurs.
Edit Variant - click to open Edit Project Variant dialog to edit a variant.
Detailed Report - click this button to open the Variant Report dialog to generate a detailed variant report.
Drawing Style - click this button to access the Variant Options dialog from where you can define how non-fitted components and varied parameters will appear, both in the compiled document view of the schematic and in schematic prints. You can also define appearance for these components in PCB assembly drawings.
Fit to Width - check this option to adjust the width of the column.
