You can simultaneously move, rotate, and scale a group of objects using the Transform editing tool.
To move, rotate, or scale an object
If you chose Select, use any AutoCAD selection method to select the objects you want to transform. If you chose Layer, enter the names of the layers you want to transform.
For example, to transform an arc, you might click one of its endpoints.
The relative positions of the destination points determines how the objects are rotated and scaled. For example, if the new points are perpendicular to the original points, the selection will be rotated 90 degrees. If the new points are closer together than the original points, the selection will be scaled down to fit in that space.
