How to delete Polygons within a bigger polygon?

[NataliaGutierrez2]

Hello,

I am working with a parcel shapefile of an entire state. I need to remove all of the building polygons falling inside the bigger parcel polygon. These are not donut holes but instead separate polygons.

I can't erase each polygon manually because I am working with the entire state dataset.

What geoprocessing tool should I use?

I have attached an image below:

Thank you!

Dan thank you for your help.

I was able to use 'Completely Within" by duplicating the feature class since this tool only works with two feature classes.

This was the problem I was having.

Yes, as in my initial response, you need to use the same file for both inputs.
