I am using the Select by Location tool to select certain polygons on my shape-file layer. I start by having a given point as my Selecting Feature and that its relationship is completely_ contains. After I run the tool the first time, I get the polygon feature that my point is in (lets call it Polygon A). When I run another select by feature tool that its relationship is boundary_touches my Polygon A, I get a layer that also contains Polygon A and the features that share boundaries with it. Is there a way I can prevent this from happening? Meaning that every time I run the select by location tool it doesn't select polygons from the previous time. Or is there a tool or a way that will allow me to join multiple layers together and remove duplicate features? I have tried the Union tool as well as the Intersect tool. Any suggestions?
