Is there a way to manage DWG-file geometry through layers in real time?

I’m trying to figure out are you able to get geometry and their layers from DWG-file to grasshopper, for example:

I have 2 polylines in 2 different layers in autocad file, I want to separate them by their layers in grasshopper. Am I able to do it so, that I can update the dwg-file and it updates in real time in grasshopper? I tried this through TTToolbox, and I could not get any attributes from it, only geometry.

Thank you for your answer! Do you know why does it give me error:

  1. Solution exception:Object reference not set to an instance of an object.

You can use native Grasshopper Rhino components to bake geometry into layers.

Is your Rhino installation up to date?

Importing a *.dwg as a content and block definition both works here in Rhino 9 Grasshopper.
