The layout editing tool presents groups of layout objects in a layout on a display of the host, wherein each group comprises one or more layout objects sharing the same or similar topology in the layout. The layout editing tool enables a user to select at least two groups of layout objects by directionally and continuously moving a cursor across each group of layout objects along a respective directed single line, wherein each directed single line intersects with and selects one section of a group of layout objects. The layout editing tool then performs a layout operation on the sections of the one or more groups of layout objects all at once based on metadata and/or one or more design rules associated with the groups of layout objects. ## Claims ### Claim 1 A system to support selection and operation on multiple groups of layout objects, comprising: a graphic-based layout editing tool running on a host, which in operation, is configured to present a plurality of groups of layout objects in a layout on a display of the host to a user, wherein each group comprises one or more layout objects sharing the same or similar topology in the layout;

perform the layout operation between the identified sections of the same group of layout objects. ### Claim 12 (depends on 1) The system of claim 1, wherein: the graphic-based layout editing tool is configured to perform the layout operation on a subset, but not all, of the layout objects within each group of the layout objects. ### Claim 13 A computer-implemented method to support layout objects selection and replication, comprising: presenting a plurality of groups of layout objects in a layout on a display of the host to a user, wherein each group comprises one or more layout objects sharing the same or similar topology in the layout;
