Multiple Drawings (MDE)

The best way to copy an object from one drawing to another is with a right-click and the 'copy" or "copy with base point" option. (it allows more accurate placement

However,you can also use "drag and drop" to copy objects from one drawing to another: Select the object, press the control key and pick and drag the object from one drawing to the other. (this cannot be done if a grip point has been selected)
