The first macro uses select by proximity to add features in one set according to their position relative to other sets. These sets can be in the same layer or in different layers.
The second macro excludes features from the set by proximity. If you want to filter sets according to their VIsibility status, all you need to do is add an IF/THEN condition using GetDisplayStatus() within the FOR/NEXT statement in each macro Regards On Thu, Oct 4, 2012 at 4:02 PM, swag_ner_pth <[email protected]> wrote: > ** > > > Hello Armando, > > I appreciate your effort to help.
