Hi @RobDraw,
The Group Filter button in Layer Properties Manger in AutoCAD 2016 is the second button from the left. When this is selected, a new Group Filter is automatically listed and allows the user to rename it. If the user rt-clicks this new group filter, there is an option to select layers that belong to this group. There is not an import or export function associated with this feature.
Inserting kevin.decavele's block does not create the groups in my drawing either.
Now, if I misunderstood that the intent is to create a Properties Filter, that is done by clicking the first button on the left. A new window opens that allows the filter to be named and the bottom portion of the window allows selection of properties to be included in the filter. Again, there is no import or export feature associated with this feature.
Lastly, the third button is to start the Layer States Manager. This feature allows the user to save the conditions of layers such as color, visibility, linetypes, etc..
Layer states can be imported and exported for use in other drawings.
I hope that this clarifies my prior post about using Templates to enable the groups for new drawings or to seek out a customization routine that can create the groups on the fly in existing drawings.
