ok i found the script and there seems to be and edit mode for created object
but i did not save the web page for this one !
but here is the code for it

bpy.ops.mesh.primitive_gem_add()if you save this code in the .blender/scripts/op folder, it adds a menu
hope you can copy it
don’t remember what the web page was for this one cause i did not save it!
seems that the panle will be visible only when cteated object by this script are selected
and then you can go into edit mode
if you find the web page for this let me know i’ll save it this time
salutations
