To the best of my knowledge, you cant very easily. This is b/c Autocad sets aside a separate memory space for each drawing. Thus a command in one would not be seen in another. However, you might be able to use BeginCommand and End command in VBA to trap the zoom, store the coordinates, and use For Each Doc in collection, zoom to coords. This all assumes that ea of the drawings is located in the EXACT same spot with regards to the others. i.e. 0,0 is the same spot in all the drawings
