You can copy an object into another file using the Copy and Paste menu commands or, using the drag and drop function, by copying it directly from the Objects window into the file. To do so, click the name of the object, hold down the mouse button and drag the object to the drawing sheet of the other document. Now release the mouse button. The object will be copied to the other document. If you have imported or placed files and are working in 3D mode, when copying, the drawing also opens in 3D mode in another document. In principle, all 2D, 3D and object information is also copied, so that you can continue editing the objects in the same way as in the original file.
