The Copy command allows the user to copy an object to the clipboard, this can then be used later in the same drawing, an existing drawing, or a new drawing. This is not to be confused with the Copy Object(s) command which has different functionality and will be covered further in this help file.
The Copy command is selected from the Edit menu ( Edit > Copy) or by selecting the Copy Icon 
from the Edit toolbar or by typing COPYCLIP into the program . Opus also supports the Windows shortcut of CTRL + C for copying selected elements.
Using Copy can be done in 2 ways. If Copy is chosen, with no elements selected in the drawing, you will be prompted to select the objects that you wish to copy.
Select the objects you wish to copy and then right click or press the Enter key to apply.
If the objects have been selected and the Copy command is chosen then the objects will be copied straight away.
Cut objects are stored in the clipboard and can be pasted back into the same drawing, another development, or into a new drawing. The objects Copied will remain in the clipboard until replaced by another Copy command or a Cut command. Objects in the clipboard can be pasted into a drawing multiple times.
