An automated system, and method of operating the same, for assisting the layout of components and the routing of conductors in a layout of an integrated circuit. An asymmetric zoom command is provided, by way of which the user can magnify the current view of a portion of the layout in one dimension while maintaining the original magnification in the orthogonal dimension. The commands can be conveyed by keystrokes, or by a command in combination with a drawn rectangle indicating the extent of the asymmetric zoom magnification. Both asymmetric zoom-in and asymmetric zoom-out are supported.
