How do I cut a page in half.
I have an 11x17 map produced in Illistrator.
I need to cut the page in half, roads, background ect.
I need to make a seperate map out of each half.
If you are lucky, you may create a line where you want the division, and with that selected Object>Divide Objects Below.
There may be some cleanup with removal of segments and the like.
And you may have to do other things, too/instead.
You can also take a slightl different approach by simply duplicating the art say to two different layers.
Then drawing a rectangle over half the map on one copy of the art and making a clipping mask.
then do the same to the other copy making the clipping mask on the other side.
As far as divide ojects below it does divide objects below but yoy only select the line the objects below have to be unselected in order for it to work.
If the objects below are selected it won't work.
If your purpose is printing, you could create two new artboards (each 11 inches wide X 8.5 inches tall) and place them one above the other. Then copy or drag your map over to the new artboards. Save the first artboard as a PDF and then the second artboard as a PDF...
This is non-destructive and won't physically divide all your paths and objects, but it will produce two halves of your map for printing.
Jacob's method allows for editing of each half, you just have to make sure all the changes to one half line up with the changes to the other half.
You start with your map:
Add a line at the halfway point
Choose Edit > Path > Divide Objects Below
When you do this, it physically separates the two halves (that's why you need to make sure any changes on top reflect the change on the bottom)
Wade's method allows for editing of both halves.
Create a rectangular frame of 11in X 8.5in (half of your original map)
Select All (Cmd+A) and choose Edit > Clipping Mask > Make
This will hide everything that isn't inside of the rectangle you created.
Now just repeat the process for the top half (You will have to make a duplicate copy of the original map on a new layer and then create a clipping mask for the top half).
To make changes, double-click inside of the clipping mask and make the changes.. When you get out of isolation mode, the mask will keep the map clipped at the same location but your changes would show up inside.
If you need to make changes, start from the original map, make your changes, and follow these steps again to make new clipping masks.
The method I outlined above allows for editing of both halves.
Using the Artboard tool, create two identical artboards (11 inches wide X 8.5 inches tall) and stack them one on top of the other (to make a total area of 11 inches wide X 17 inches tall). Move your map over both the artboards with the middle of the map falling right where the artboards meet.
When you're ready to save or export your map, choose your desired format and where you see Range in the Save As dialog box just type in the number of one of your artboards.
In my example above, Artboard 03 is the bottom half of the map.. so I would type 3 for the range.
Then I would repeat the process for the other half of the map (02 Artboard), and type in 2 in the Range box. Boom! Now you have two halves of the map saved.
If you need to make edits, go ahead and make the edits in the Illustrator file and then resave each artboard again.
In conclusion, all the above methods do mostly the same thing, but have different approaches. You may find that you prefer one of the three. The decision should be based on your ultimate goal for the map and ease of understanding.
I hope this helps.. I know it was a long one!
There is actually another way to use my method that might appeal to you.
You can save the 11x17 file as is and then place it into another document with two artboards 8.5x1l or if horizontally divided then 17x5.5 then after properly postition a linked copy of the use the clipping mask for one side and then place another copy for the other art board and make the second clipping mask.
Now if you neeed to update the art use the linked original and set the link options to automatically update.
That way you only have to update the art once. Of course this is only good if you need both halves to be updated in the like manner.
And if the the two halves have to be separated by a space. If no space betweent them is required than the previous post mjarrott is the best way.
If you need a tutorial I will do a video tomorrow.
