If you wish to Cut, Copy, Clear, Drag, Mirror, Rotate, Elevate or Duplicate elements, they must have at least one node inside the Marquee area in order to be selected. The edit operations will act on the whole element.
To use Edit commands on a placed Drawing, include at least one node of the Drawing (i.e. one of the Drawing’s corners) inside the Marquee.
Note: In Section/Elevation/IE, 3D Document, Detail and Worksheet windows, some editing commands are available only for 2D drawing elements.
