I'm attempting to split a feature class of polygons by another set of polygons. The steps I've taken are synonymous with those here. I select the polygons I want to use as the split, and edit using the "split polygons" tool the feature class I am trying to split. I end up with funky results as I show in the following picture:
Wherein the red lines are the polygons I want to use to split the black polygons. The selected polygons are a single selected polygon I am using to demonstrate the funky result I am having. Additionally, some other polygons split like they should normally, though replicate themselves multiple times in the results.
