After our recent discussion on this topic I read somewhere (cannot find it now) that one could control the 'colour by map' feature so that sub-maps <x> levels down from the primary maps selected could be coloured, and that the way to control this was with the select command. (This would be a useful feature - select a single primary map to enable Therion to determine the overall output pdf title, but have the various sub-maps coloured and labelled in the legend) (And another thought, perhaps sub-maps would have their own pdf layers as well??) Following the Therion Book I tried; select MiddleEarthPlanMap map-level 1 however with 5.3.10 this produces an error. "error -- thconfig-MiddleEarth.thc [32] -- unknown option -- map-level" Can map-level be used in the way I described above? What am I doing wrong with the select syntax above - Therion Book suggests it should be OK? Thanks Bruce
