Notice that Only the traces on Top Copper are Selected
Finally, use the icon at the far right of the selection filter to deselect items that are only partially
inside the tagbox; in our case this will deselect the track we manually placed from J2, pin 4.
Tag box toggle
We can now simply hit the delete button on the keyboard or right click inside the tagbox and
select Block Delete icon to remove all the top copper tracks.
Bear in mind that the selection filter controls what objects are available for selection
at any given time. If you ever find that you can’t select an item the first thing to
check is whether that object type is enabled for the mode that you are in.
Alternatively, simply switch to Selection Mode where all items are selectable.
Advanced Auto-Routing
Given that we’ve ripped a lot of partials and removed vias as well we’ve actually made a bit of a
mess here. Fortunately, we can fix the situation by simply re-invoking the auto-router and re-
placing all our tracks. The router has its own clean up phase so it will tidy up all the redundant
partial tracks for us as it completes the new routing.
If you have a standard features version of Proteus (PCB Starter Kit, Level 1 or Level 1+) simply
run the autorouter as we discussed in the previous section to re-route the board.
For those using the Advanced Feature Set, we’ll use this section to show in brief some of the
additional features available. These fall into two main categories:
The ability to route only a specified area or set of connections.
The ability to control the routing script; i.e. to determine which routing commands are
executed and in which order.
