I am looking to trim several regions to a boundary curve, but what would be the best way to proceed?
What I need to do is trim the street network I generated earlier to the boundary curves for a project. There may be several boundary curves that intersect a single street network, but this example includes only one portion of the street network.
To be clear, I want to transform this:
To this:
Hello,
Here is one idea.
The first few components could be avoided if the curves were clean and closed.
Thanks, the intersection approach helped me to determine a good approach to move forward with. Generally, with an interconnected street layout, there’s only a single exterior curve for road outlines, which is longer than its interior curves. So I did the region difference with the project outlines that intersect the exterior road outline curves. 
E: This is just a matter of prepping the data so you can apply a region difference between the boundary curves and the intersecting curves.
