Is It possible to copy/paste something from a map to another?

Like TheNoAuthor12 said, you need export (File>Export Selection) the selected object(s) and open up the other map and do (File>Import Objects). (Note: You can't Export Compound Objects)

1. Start selecting each piece individually. And every now and then bind it into a Compound Object incase you lose selection and can't undo back to the selection.
2. Once you think your done, make it all into a Compound Object and move it around. Find any stragglers you missed and include them in the Compound Object.
3. Once that is done, remove the Compound Object so it's all individual white outlined pieces and do "File>Export Selection". Personally I would put it into a folder in your CS directory like "exported".
4. Go into the other map and "File>Import Objects" and you it will be imported into your map. (Note: The area it spawns I think will be relevant to where you Exported it from the other map. So don't be alarmed if you can't find it at first. Look around and you will spot it.)

Edit: Dang it statyk, you posted when I was just starting on mine!
