I am looking to trim all polylines outside of a polygon, so that when data is requested, I can send only data in that requested area. I tried selecting by location, but the issue is that there are many polylines, some which fall completely within, some that fall completely outside, and some that cross the boarder of a polygon. I need everything to bee trimmed so that the polylines do not go beyond the polygon boundaries. It would be even better if I could specify a buffer distance from that polygon. Does anyone know how to do this?

 

Thanks!

I tried that, but the polylines ended up being messed up - like they were straightened out. But, after researching the intersect tool, I found a similar tool called Pariwise Intersect, that seemed to work great. http://www.arcgis.com/home/item.html?id=120807ac7f8449f89840ae48e87d7f55

Just use the "Intersect" geoprocessing tool and intersect the poly with the polylines. Output will be what you are looking for.
