Start the pattern creation by invoking Pattern Editor from
the Utils menu in PCB. Create desired primary pattern by using
Pattern Wizard or by doing it manually.
Decide
how many alternate patterns you want to have for this component and
assign meaningful names to them. Go to Pattern » Add Pattern
Graphics dialog. Inside, you can enter all your alternate pattern
names into the Existing Pattern Graphics list. This list is a pool
of alternate patterns for your component and can contain more then
eight alternate pattern names, however only eight alternate patterns
can be assigned to a primary pattern for any one variant of a
component.
For example, if you were to create sixteen alternate patterns
named 1 to 16, you could then create variant A of your component
with alternate patterns 1 to 8, and then edit variant A to create
variant B of the same component with alternate patterns 9 to 16 from
the list. This alternate patterns name list allows any 8 to be
selected for any variant of the component, including duplicates.
Once you have finished entering names for alternate patterns,
close the Add Graphics dialog and select Next Pattern Graphics from
the View dialog. You will be presented with empty workspace to allow
you to create the next alternate pattern. The title bar of the
Pattern Editor Window will show the primary pattern name, followed
by the alternate pattern name being edited, separated by a
semi-column.
Create all the alternate patterns you need in the above manner and
use the Validate option from the Utils dialog to ensure that all
patterns you have created are correct.
Go to Utils dialog again and select Orientations option. Here you
can choose which pattern out of your list will be your primary
pattern and which other 8 patterns will be assigned to top and
bottom orientations.
On the left side of the Utils Orientations dialog, you will find Top
(or Component) side orientation options of 0,90,180 and 270 degrees
of rotation. Likewise, the right side of Utils Orientation dialog
provides Bottom (or Solder) side orientation options with the same
degree assignments. By clicking on the down arrow button on the
right side of each assignment, you expose and select which alternate
pattern name will be assigned for a particular orientation and/or
primary pattern. When all required names are assigned to their
respective orientations and/or primary pattern, click OK and exit
the Utils Orientations dialog.

To save your new component variant, go to Pattern
dialog and select Save to enter into Pattern Save to Library dialog.
Inside this dialog click on Library button to select destination
component library for your pattern, type in pattern name, tick
create Component box, and type in Component name.
Finish by clicking OK button and exit. You have successfully created
a PCB portion of a component with multiple alternate patterns, so
you can finish component creation by creating a corresponding
Schematic symbol inside Symbol Editor, followed by the Library
Executive, where symbol and patterns can be merged to create a
complete P-CAD component.
