Fanout is the via and trace pair that is connected to a surface mount pad.
It allows connectivity of the signal from the surface layers going to the inner
layers of the board.
In this tutorial, I will discuss with you the procedures on reusing fanout of surface mount components and the option of reusing them in an array of surface mount pads.
1. Let's assume that you have placed all your components on the board,
and the placement has been cleared of violation and clearance errors. Fanout of surface
mount components will have to be done prior to routing the whole board. In this case,
we will do manual routing/layout if the board as opposed to using the Autorouter feature
of your PCB layout software.
To start with, click on the Interactively route Connections.
2. Alternately, you may go to Place and select Interactive Routing
on the dropdown menu.
3. The cursor changes and this indicates the you are in the interactively routing mode.
4. The pads or vias can now be selected for routing. A circle appears with the pointer to indicate the center of the pad or via being selected for routing.
5. Drag the mouse to the direction you want to route and trace will appear from the pad or via.
6. At a point where you want to have a via on your connection, press '2' while routing.
Note:
This is the shortcut command to add via while on the routing mode.
Press 'ESC' to terminate the routing and the via will end in place.
7. Select the via and the track/trace. This is done by selecting either the via or the track/trace first then hold the SHIFT key and select the other object.
8. To copy the fanout, use the CTRL + C command. An alternative would be Right Mouse Click and select Copy from the menu.
The pointer will change to a big crosshair and will then allow you to select the center/origin to which your copied fanout (track/via) will be referenced.
9. Use the CTRL + V command or Right Mouse click then Paste from the menu to paste the copied fanout.
Position the pointer to the location similar to the reference pad or via from which it was copied. Click on that location to end the process.
Continue as needed to the other pads or vias with similar properties for the fanout.
Reusing fanouts in an array is very helpful in reusing fanout for surface mount IC's (integrated circuits).
Below are the procedures:
10. Assuming you have copied the fanout from Step 8.
Go to the main menu on the PCB workspace, then select Edit then Paste Special.
11. A popup window for the Paste Special settings.
Check Paste on current layer and click on Paste Array.
12. Paste Array setup windows appears and it allows you to
set the values for:
Placement variables
Array type
Linear Array
Circular Array
13. Select the pad for the start of the fanout array.
Then, click on the selected pad.
14. The fanout have been reused in an array of pads.
Hope this helps.

The sequence is:
select something
Ctrl C
Click a reference or base point, maybe the end of the track in this case
Ctrl V
