This should be a simple task. I have a large simple polygon, a US County, and another shapefile of small polygons that fall within that County. I want to create "holes" in the large polygon where the small polygons occur. Here's the rub. If I select one of those polygons, and start editing the large polygon, the CLIP option is available and functions correctly. If, however, I select two or more polygons, the CLIP option is NOT available...most importantly, I would like to select ALL of the small polygons and CLIP them in a single action. When I do Select All of the small polygons, however, as when selecting just two, the CLIP option is not available. Can anyone tell me what I am going "wrong" or why this is the case.
