Cut and paste - but when copying views, you need to paste them into the sheet object in the tree. (not in the workspace)
Additionally, if you don't need associativity, you can right click on your view, go View X (whatever it's called) and select "isolate". Generally, you will want to isolate generic re-useable views.
Here's a trick: Create a Detail, copy the geometry from the source view into the Detail, instanciate the Detail in to the new view, explode and delete the detail.
