I have created somewhat of a world map of my own (for Dungeons & Dragons reasons) in Illustrator so that I can have a master document of the world at large and would now like to take a smaller part of the bigger map to create a more detailed section of it.
Is there a way to crop the paths I have created for the landmasses to the size of a smaller Artboard while keeping the paths and layers intact? I would like to basically take everything inside the Artboard (the black outline in the screenshot I provided) and discard everything around it while preserving the separate paths and layer structure as far as possible so I can scale and edit everything inside the Artboard.
The entire document is a bit too large to be scaled up entirely just for the small part that I want, my PC would certainly not handle that very well. I have so far tried to create a rectangle the size of my desired Artboard and creating a Clipping Mask for it as well as using the Pathfinder tool to crop or intersect etc. but all those leave me without control over my original layers.
Is there a way to do what I am looking for and being left with only the parts of the paths inside my desired Artboard? I would very much like to be able to continue working with paths rather than rasterizing the part I need.
Best regards, Panicmode
Edit: I have in the meantime, using some of the very useful tips Kyle has provided, found a way to mostly achieve what I was looking for. Copying the layers while preserving the layer structure I have used the Eraser Tool to erase around my new Artboard, which keeps the paths inside the Artboard intact. Everything not needed outside the Artboard can then simply be erased. I wish there was a simpler way to achieve this same result, but so far I have not found a way.
