I wan't to make a large area overview map. We have centreline data for all of it, but only some caves have been drawn in therion. How (is it possible) to show the caves with therion data in outline form (i.e. walls only), but the other caves in centreline-only form. I can get it with them all showing centreline and therion caves showing walls, or walls only, and nothing at all for centreline-only caves, but not what I want. Does the revise command help here? I know select terikanplan@terikan.Mulu selects the map terikanplan but I'm not sure what the correct syntax for selecting a centreline is: would it just be terikan.Mulu? or terikan@mulu?
