How to retrieve the structure of instance up to model?

[areal3d]

hello,
i just stuck at one point:

wirh onmousemove i can get the instance/component - structure easily:

pickhelper = view.pick_helper pickhelper.do_pick(x, y) pickhelper.count.times { |pick_path_index| pp=pickhelper.path_at(pick_path_index) }

i can the iterate pp and get for example all transformations.

now when i iterate thru entities of a certain instance and want to get the parent, i do not get the higher INSTANCE, but the DEFINITION LIST.

how can i get the whole path as in the pickhelper from a selected instance?

thanx a lot for helping .

edit1 : found this interesting topic:

What is the way to get an instance path to the root given a Group/ComponentInstance?

The only thing I found close is InputPoint#instance_path, but it works only based on x,y coords which I think may return wrong results if the point that is used is shared by several instances Using Make 2017

starting to check it out!

edit 2:

this works, but interesting:

not the returned arry of elemnts holds the row, but the array[0]

BUT IT WORKS FINE !!!!

Instances do not have Entities collections. Only definitions and the top-level model have an Entities collection.

You will either need to build an InstancePath as you drill down or get the Model.active_path and add the selected instance to it.
