Clipping mask on multiple layers of map import

[Charlie329572228uvx]

Hi,

I am trying to use the red rectangle to clip / crop the map so that I can export a selected portion of it. I am not sure how to apply the clipping mask to all of the sublayers of "Zaragoza Sync 1"

@Charlie329572228uvx it needs to be the on the top layer and select all, Command 7 (MAC) or Control 7 (PC) to mask within the red square. Or Go to Object > Clipping Mask > Make
