Hi Pilou, those are variants of copy and paste that are similar to orient.

The Ctrl+Shift+C does CopyClipboardWithOrigin - it puts the selected objects into the clipboard same as regular Ctrl+C but also allows you to pick an origin base point. This part is similar to first stage of the Orient command where you pick the base frame.

You can get the same kind of thing with regular Ctrl+C copy if you set the cplane origin to the spot you want for the base point.


Then Ctrl+Shift+V does PastePart, which pastes in the objects from the clipboard and also allows you to position them - this is like the second part of the Orient command.


You can also use the Orient command to do the same kind of thing as well.


These are part of a set of 6 commands (Orient, OrientLineToLine, OrientViewToView, CopyClipboardWithOrigin, PastePart, and ImportPart) related to orienting objects to new positions, see here for some information on them:
