So I have a file with geometry, linked by Shared Coordinates, while my rooms are in the host model: [image] However, after selecting all the rooms’ geometry and doors, windows, walls, etc from the geometry file, they appear to be on completely different places: [image] Any ideas why? …

That’s cool, could you please share the script? I tried different options and I still can’t get it to work, here is the geometry from the host model (blue) and the one from the geometry model (red). You can see the different transforms and none of them intersect: [image] [image] [image] From…

Sorry for the delay, here’s the python code which takes a document (linked instance) as input and outputs the linked document’s total transform as a point. #Written by Scott Lebow import clr clr.AddReference("RevitAPI") import Autodesk from Autodesk.Revit.DB import * clr.AddReference("RevitNodes"…

Thx, Scott! That brought me as close as I could get so far: [image] [image] However, there is still a weird rotation angle, while the BasePoint reports that angle to true north is set to 0…: [image] I am now trying to find out where that comes from :slight_smile:

Try BimorphNodes LinkElements they already include built-in logic to handle the transformation of linked elements and their geometry in the host document.

I tried that initially. I finally got what I needed from GeniusLoci’s Get Project Locations node. For some reason, nothing else could read the True North correctly: [image] The node also reads the coordinates as it should - returns identical values with the one from Scott’s script. So I will just…

Its a problem with the Python script as it converts the transform to a translation and you need the former not the latter to position the geometry correctly. You could convert the transform to a Dynamo CS in Python using ToCoordinateSystem() or achieve your workflow with significant performance impr…

I wanted to thank Danail momchilov, ScottL and Tomas mahon for their contributions, I was dealing with this issue all afternoon and I finally managed to get the revitlinkinstances geometry location in my host model. If I get consent from my work staff I can publish my script which transforms all wa…

Diving further after this topic and as an alternative to the solution Thomas provided, I found a node from the amazing archi - lab package, that lets you select elements from linked models directly and returns the total transform as well: [image] you could then get their geometry and use the tran…

Hi Thanks for your contribution, I have tried using the transform.TocoordinateSystem() method.Its working very slowly so Im using the bimorph nodes and it seems to be faster.Are you using the archilab package and then transforming elements to designscript geometries? and/or the bimorph nodes? Do yo…

I depends on what you are trying to achieve. I have been using both for different purposes. The archi-lab node lets you select only certain elements from the link instance. Then in combination with geometry.transform node it works quite well for me (and fast). In case I need a whole category of elem…

thank you ! glad you found it useful

edit: it’s actually Dimitar Venkov we should all thank
