Copies the selected item(s) to the clipboard. The contents of the clipboard can later be pasted with the [link=paste]Paste[/link] command. The [link=copy]Cut[/link] command can be used to copy items to the clipboard while also deleting them. If text in an editable text field is selected, that text is placed into the system clipboard, and the copied text can be pasted into any text field within Stem3D Modeler, as well as any other application on the system that recognizes clipboard text. If the selected text was copied from a field representing a floating point number value, in addition to placing the decimal string representation of the text on the system clipboard, the raw floating point number is also placed into a separate internal clipboard. This allows losslessly copying and pasting floating point values regardless of the accuracy of their displayed decimal string representation. For this behavior to take effect, the entire text field must be selected; copying a substring will not carry a lossless floating point value along with it. See also [link=number_storage]number storage[/link] for an additional way to move floating point values from place to place. If no editable text field is focused, selected mesh geometry is placed into an internal clipboard. This does not overwrite any text or floating point numbers that may have been previously copied, nor does the reverse happen. If the copied selection includes faces connected to adjacent unselected faces, pasted faces will not be connected to their previous adjacencies. [!todo]Currently, only vertex and face data on the Mesh Editor screen can be copied and pasted.
