The Geo3D group format (that end with .grp) is very simple: The first line contains the required header ##Geo3D_Groups. Comments start with the character #. There are only two commands: A menu item command begins with !M followed by its name in quotation marks ("my name"), followed by the position numbers of the 3DMF objects. the position numbers are separated by spaces. “-” means “to”; 1 - 5 means “all objects from 1 to 5”. The 2nd command, !S, inserts a separator line.
The following example is part of the Geo3D package (corresponding scene: Menu “File / Show Demo”:
##Geo3D_Groups # required header
# Comments start with the character '#'
# !S: Separator # !M: Menu Item # '-' means 'to'
!M "Erato" 1
!M "Euterpe" 2
!M "Polyhymnia" 3
!M "Klio" 4
!S
!M "Erato meets Polyhymnia" 1 3
!M "All but Erato" 2 - 4
!M "Euterpe and Klio" 2 4
!S
!M "Show None"
