Exclusion Zone when using Tools - Auto Route - All Nets

So, I am using DesignSpark PCB 8.1.2, I have completed my schematic and assembled mainly SMD components on the top side of a simple 2 layer board.

Before I use Tools - Auto Route Nets - All Nets, I need to create an exclusion zone to stop the autorouter placing track and/or vias within that zone.   Typically, this would be used to prevent track being placed in or under an antenna area and/or under an IC to so as not to interfere with specific thermal vias being provided later.

I have read a couple of articles about copper pour shapes and keepouts but as yet not been sucessful in stopping the tracks/vias entering these supposed 'no-go' areas.

Your help is greatly apperciated. Thanks..

Yes the keepout is just for the poured copper.
I suggest trying to place a physical barrier, draw a copper area to represent the "do not route area" and assign it to a new unused net, after routing delete the copper areas.
