I have a python script that gets all Subassemblies in the Maingroup and Offsetgroups. Part of the list: [image] and [image] Problem is how to get the right output? Each subassembly has a handle (by subassembly.Handle), but the line below doesn’t work. ssel = SelectionByQuery.GetObjectByObject…

[image] Civil 3D Toolkit 1.1.32 it also returns the corridor feature lines in the OffsetAssemblies

The SelectionByQuery class won’t work because subassemblies aren’t implemented with the OOTB nodes. And then with the Toolkit, is there a public constructor? Or have you tried casting?

I don’t know how to cast an civil object to dynamo in python. Can you provide me with an example. In python / C# or vb .net? I think it is used it in the node “Assembly.GetGroups” and many others.

Sorry, I misread your initial post. A cast isn’t the right thing to do here since you’re trying to go from a base class to a derived class, not the other way around. The Civil 3D Toolkit doesn’t have a public constructor for the Subassembly class, but you could use the GetSubassembliesByName method…

Hi, I can’t get it working. Below is the complete script and a sample file. The goal is to get a complete list of subassemblies (mainline assembly and offset assemblies). After that is can create all the parameter/values… Attachment: Cor_get_assemblygroups_v2.dyn (30.6 KB) COR-Offset-Assembly.dw…

Hi @zachri.jensen , The GetSubassembliesByName returns all the Subassemblies in the model, but not per Assembly. I need to select the Subassembly per Assembly. The goal is to extract the Featurelines and Parameters/Values from a Assembly with Offset Assemblies in it. The node in the Civil3D Toolkit …

Hi @JPS , If I understood correctly, you need a few parameters for every subassembly for all assemblies in your drawing. I don’t know if this works for you, but have you tried the following nodes? [image]

I can’t seem to find a node to solve your problem in fact. However, if I were you I would try to use assemblies without the offsets groups. Instead, I would try to incorporate the offset subassemblies in the mainline assembly using using something like ConditionalHorizontalTarget or LinkOffsetAndEle…

Hi Paolo, Thanks for updating the Toolkit. But still my question has not been answered. “Problem is how to get the right output”

Yes, i tried the nodes, but the node “Assembly.GetGroups” only reads the Mainline Assembly, not the offsets. see my other thread " Issue with Extract corridor feature lines".
