Is there a way to rotate these objects to different angles or is it just strickly copy and paste into the same orientation as there origanals?

You can rotate objects either individually or as a group in total. To do this by increments use the numeric keypad.

1 = left 33 degrees (or thereabouts0
4 = left 16 degrees ...
7 = left 7 .....
etc etc

In the second pull down menu in your map-maker there is an option 'rotate objects'

If this is clicked 'on' then you can rotate whole groups of selected objects and keep them in the same relation to each other while they are rotated. For instance, with 'rotate objects' turned on, you can rotate an airfield in it's entirety, without each object moving around its own individual axis. This way, all groundplates and runway plates will remain nicely aligned in a straight line.

If you turn the option off, then each object will rotate around its own axis and totally mess up a runway, or a wall or whatever alignment. Actually I cannot think of any reason to keep this option turned off.

Also when rotating, take care that no single, individual object is selected. To unselect a single object, use right click with mouse and select 'deselect' option.

This is important, because even when whole groups of objects are selected (with alt+mouse drag) you can still select individual objects which will be rotated as a priority over the whole group selection.

Sounds complicated perhaps, but just try it out a few times ...
