I created an asphalt-like pattern in Illustrator so I can create a street. I followed a tutorial to make the street pattern, and the shading goes up and down. So I distorted the image so it goes at an angle, to be consistent with the perspective in the image. However, the image now goes partially off the artboard. So I put a frame around it and tried to use the shape tool to trim off the excess bit of the street. But when I do that, the pattern remaining changes. Is there a way around this? I hope I’m explaining this well.
I would just create a path which covers all the areas you want to keep, and then create a clipping mask.
Make your clipping path on top, select all the paths and Right click → Make Clipping Mask (Ctrl+7).
The good thing with a Clipping Mask is that it’s non-destructive, meaning you can easily make changes and fix things.
