When toggled on the selection applies only to the layer specified in the layer selector
The other buttons represent different object types (tracks, components, graphics, etc.) and
determine whether those object types are selectable. Hover the mouse over an icon for a tooltip
description.
If you switch between the different modes of operation (for example from selection mode to
track mode to component mode) you will see that the selectable object types will change
according to the mode you are in. Whilst these are good defaults for normal operation you can
change at any time simply by toggling on or off the layer switch or object type that you do or do
not want to be selectable. If you find yourself changing selectable items regularly you can also
change the defaults via the System Menu – Set Selection Filter command.
The Layer Selection options
Let’s take a practical example and delete all the traces on the top of the board, except the one
we have manually placed. Start by entering Selection Mode and left dragging a selection board
around the entire board.
