the mouse up and right from the bottom of the board edge until the co-ordinate display reads
correctly (you may need to switch into Metric units using the ‘M’ shortcut key toggle).
If required, we can move the DC/DC converter circuitry as before, then switch back to pad mode
and place the final mounting hole at the correct co-ordinates.
Alternatively, having set the output origin and knowing the co-ordinates you can
right click on the mounting hole and select the move-to command from the context
menu to programmatically position the part.
With position sensitive components it is often useful to ensure that they cannot be nudged or
moved inadvertently after placement. You can lock any object in position by moving the mouse
over the object until it is encircled by a dashed line, right clicking on the object and selecting
Edit Properties from the resulting context menu. The Lock Position checkbox can then be
selected to prevent movement or deletion of the part.
You can also set a specific minimum zone clearance for the pad to reserve some
extra space for the bolt.

We have now completed the physical layout of the board. If you decided not to follow the full
layout process you can load a version of the board in its current form by opening the home
page, clicking on the Open Sample button. The project you want this time is the unrouted
dsPIC33 Recorder project from the Tutorials category.
