Then, the “middle” edge is subdivided, affecting its new “sub-quad” as described above for only one edge.<br /> *When four edges of a face (a quad) are selected, the face is subdivided into four smaller quads.<br /> <br /> {{clr}}<br /> <br /> ==Options==<br /> These options are available in the {{Literal|Tool Panel}} after running the tool;<br /> <br /> ;{{Literal|Number of Cuts}}<br /> :Specifies the number of cuts per edge to make.
