The script creates an empty (those things with axis and no mesh-data) and sets it as a parent for the selected objects. After installing you can trigger it with pressing P, you can change this shortcut in the user preferences later.
v1.3: -works with blender >=2.8, access also through "Add" menu -new objects will be selected
How to install :
- goto Blender -> Edit -> preferences -> addons
- on the top click "Install", then browse for the downloaded zip file and click install
- you should find it now in the Addon-list as "Object: Add an empty as parent"
How to use :
- select the objects
- press P
- property panel "Add empty as parent" should appear
- select the Empty type ( axis, arrow, cube ...)
- select the empty position ( world center, median point, at cursor, active object )
- select whether to add one empty per object or only one with one parent per object
- set option to first set objects-center set origin to object first
- check parent inverse if you want to set the inverse
- you can set the scaling of the empty in scale field
- you can set the name of the empty in name field
- to use names of selected objects as base set use childname
