Hello I am trying to create a spherical wall made from to half spheres in PFC 3D version 7. Is there anyway to cut a spherical wall in half and assign different groups to each half? Thank you ---

Hello Mehrdad, In this case, I would create two half-spherical geometry objects (either with CAD or _PFC_ geometry logic). You can ensure that the edges of the half spheres nodes are positioned in the same location and use the `wall import` command to generate walls from the geometry. More information on this command can be found [here](http://docs.itascacg.com/flac3d700/pfc/pfcmodule/doc/manual/wall_manual/wall_commands/cmd_wall_import.html?node5212). ---

Thank you for your help.
