Using the latest version of Illustrator. I have a very large image, 210" wide, that I have clipped to a size around 120". Much to my amazment, Illustrator does not know I have clipped the image. It won't let me move it to the edge of the artboard, insisting that it is bigger than 120". What? When I clip an object that means I do not care about the parts that are that is gone. That is why it is gone. I have never had a situation where I wanted to do anything with the obscured part of a clipped image. Has anyone? Why does Illustrator think I do? I cannot believe that in over 26 revisions, Illustrator still does not treat a 120" clipped image as if it were any other 120" wide image. I bet if Freehand were still around we would not be seeing massive holes in the application like this one. Is there a work around to this? It is a vector file, so I can't crop it in Photoshop. Thanks.
I believe you will have better success if you open the image in Photoshop, and crop it there (and save as a new name if you need the uncropped versions). Then place the cropped image in Illustrator. When you go to print or have to transfer the file to go somewhere else will be faster. I would recommend the .PSD format also.
Not sure why your 210" is giving you trouble, but if you provide a zoomed out screenshot with your time slected that might shed some light on what you are doing wrong.
