automatically pick new host for all trees in revit file to be the grond beneath them

[ghada_elsagheer]

hello so I have an issue that all these trees don't have a host and the ground beneath them is divided into different parts with different levels so I can't pick the ground once for all the trees as new host and have to manually choose each ground part as new host for each tree which is taking a lot of time from me

how can I automate this on dynamo? in a way that dynamo will see the trees zxy coordinates and the zxy coordinates of the ground beneath it and pick the ground beneath each tree as its host

can someone please help

[ghada_elsagheer]

if there is anything not clear enough, I can rephrase it

Its clear. But you'd probably have more luck on the Dynamo forums.

@ghada_elsagheer 

What is not clear is the category of the host? Floor elements? 

Its Sunday but I can try to help if I have some free time but no promises. If not, I wil re-vist the post tomorrow. However, please do tell if you have already recieved help on a different forum such as dynamobim. 

Edit: A very similar question was posted nearly around the same time on Dynamo forum. Could it be that you two are working on the same project https://forum.dynamobim.com/t/aling-revit-families-to-modified-floors/109345

How about Cut (to clipboard NOT to Geometry) cut to clipboard then PASTE back into 'Same place'?

Trees do not need a host and can be free standing elements. They are not like doors.
