Hi , Lets say i have instantiated 2 cells or any number of cells , is there any command to align the cells ? with X/Y axis ? Thanks

There isn't a command to force alignment of a cell that has already been placed; there are various options to the

getcell

command that let you place an instance at the time you create it. A command that automatically aligns a cell to the abutment box of its nearest neighbor would be quite useful, though.
