I am using SketchUp Go web version in Google Chrome.
I am importing a Site Survey in .DWG as I want to drop a new unit onto the site plan (an outdoor office).
I am able to import the file and I can see it in the imported file dialogue. However it’s not clear to me how I actually get the site survey into my scene and start to draw over it.
I’m able to see all this in your import, but it is spread out over a large distance in all directions.
You need to clean up the .dwg before you import it.
I can’t advise you on autocad.
