Trying to look for how to do this and I'm kind of at a loss here.. Here's my dilemma:
I have a polygon shape, and I want to use that shape and get only the polygon data from 2 other layers that are only within that shape. Once I get those I'm going to union the resultant polygons but what would be a good second step for this? First step is getting the polygon I want to use. I did read about the clip geometry tool but it looks like from what I'm reading, that only clips on a selected extent, and not an actual input geometry. Any guidance would be wonderful. Thanks!!
so the first step is to query the two other layers using a QueryTask and the input polygon as the queries geometry. Then you can take the results of those queries and do your step two.
Ok thats pretty simple.. The only other question I have would be what spatial relationship would I use for that? (I should have mentioned that earlier) Then I can union all 3 polygons and make the final graphic right? Or just use the two? I'm asking this because I need to show the union on the map within the parcel polygon only.. amongst other things that need done with this. lol. Thanks for the quick reply on this too Robert.. You're a wealth of knowledge.
That depends. Do the polygons have to be completely contained in the selection polygon or can they just intersect?

Unioning all three would not make much sense as that would basically be the selection polygon that you started with. Maybe you would explain more about you goal. Are you looking for the symmetrical difference of the polygons or...?
1) The polygons need to be completely contained in the selection polygon.
2) What I'm doing is searching on a parcel geometry for land use and soil types so I want to show the land use and soil types within the parcel polygon. Hopefully that makes sense..
