This dialog is used to create rules which cause components to be variant by virtue of an attribute match or being in a named area or a hierarchy block. This is only available in a schematic.
Locating this option
Available in a Schematic from: Technology Rules - DFM/DFT > Component Variants tab
Using the Component Variants Tab
Navigation
The buttons to the right side of the dialog are used to navigate the grid, the general common buttons are detailed on the Technology Navigation page.
Add a component variant rule using the New button, which will create a row in the table.
Rules are applied when Apply is pressed at the bottom of the dialog.
Using the Editing pane
The editing pane looks like this:
Using the dialog
Attribute and Match
Choose the Attribute Name from the drop down list. This will define what how you want the rule to
work. The Match value is used to match against relevant fields of a component. So the
The matched value can be specific or a wildcard match.
In particular
Note, rules only apply to components which do not have explicit variants defined on them already.
The Wildcard Wizard is enabled using the small
icon next to the Match: entry. 
Within Areas
If you have any Areas defined in the design, a rule can be defined for a specific named area, or wildcard matched areas.
Variant List
This grid lists the Variants defined for the current design, and the Fitted check boxes define which variants the matching components are fitted or not fitted in. A rule should be unfitted in at least one variant.
Export and Import CSV
Use the Export CSV button to export the data in your design into a CSV format file. Using the Export CSV option will provide you with a formatted template ready for you to edit in your own data.
Use the Import button to import layers into the design using a CSV format file.
The data in the file represents a spreadsheet of dialog contents with the data headings along the top row.
