Create a Speckle stream from AutoCAD DWG 2018

I wonder of you know a way to create a Speckle stream from a AutoCAD DWG 2018 file? I do not have access to AutoCAD. I have tried to import it into Revit and it worked rather well but for some reason I lost data like colors.

If you have Rhino, the AutoCAD DWG import would probably preserve more information (like display styles and block transformations) - I’d recommend sending it to Speckle from there.

Thanks. Unfortunately I do not have Rhino, only Revit and Blender.
