This question already has an answer here:
I have a layer in ArcMap 10.2 that is one big shape made up of five smaller shapes. I need to create a layer with only four of those shapes, for the purpose of showing the difference in areas when the fifth shape is not included.
I've noticed that a simple copy and paste of the original shapefile back into the Table of Contents is not a good idea as any changes I seem to make to the new layer also affect the original layer. Is there a simple way to go about doing this? If it's relevant/useful I have the free version of XTools Pro.
