Hi , I am trying to copy the cell into north with spacing 30 -- but getting below error : % copy n 30 Copying (UNNAMED) would create a circularity in the cell hierarchy ((UNNAMED) is already its ancestor) so cell not copied. % copy n 30 Thanks in advance

You have the top level cell selected. For what you want to do, type "a" to do an area selection, followed by "copy n 30".
