Whilst it is very easy to select all objects inside a rectangle by simply ending all commands then indicating two points, can I easily select all points outside that rectangle?

There are a whole suite of tools that can be used to either select or mark objects and one of these does exactly what you are asking for.

From the Caddie Application main toolbar on the left hand side of the screen, choose the 'Select' command. If there is no 'Select' command hold down the Tab key and choose the 'Mark' command, which will change to say 'Select'

From within the selection commands, choose the MSRect command and then from the dialogue choose 'Elements Outside'. When you indicate two diagonals of a rectangle, Caddie will now select all objects outside the chosen rectangle.

Applies to:

Caddie 16 onwards.
