Script Help, Please!

[techworley]

Is there any way to write a mel script that would add a sphere to a group (parent and child) that only had one object or one group throughout the entire outliner.  Or if i could set how many levels deep to go would be nice...

Example:

Group1               
    Group2   <----  This group does need a sphere
         Cube_Poly    
    Group3   <----  This group does need a sphere
         Group4 <----  This group does need a sphere
              Cube_Poly
    Group5   <--- Nothing needed (has more than 1 group or poly)
         Cube_Poly
         Cube_Poly1
         Group6    <----  Nothing needed (has more than 1 group or poly)
             Cone_Poly
             Cone_Poly

Thank you,
~Matt

Do you define group as transform with no shapes under it? (See from scripting and mayas internals point fo view no such thing as a group exists!)

I believe a group is defined as a transform with only transforms in it and no shapes, the group command also does exactly that.

you can get all groups with ls -type 'transform' -l
you can iterate over all groups and use listRelatives -c -f -type 'transform' to get their children
then it's a simple matter of getting the size of the child list and if it's exactly 1 create a sphere and parent it to the current parentitem
