Hello, I'm still a relative newbie to FME, so bear with me. I'm trying to update our topographic CAD dwgs with our updated LiDAR derived contours. I only want to replace the existing contour layer and maintain all other layers in the existing CAD dwgs. I'm just not sure how to proceed. The contours are already clipped to the same index grid as the dwgs. Any guidance to the correct path of transformers would be most appreciated.

Thanks everyone, be safe out there and wash those hands!

To add to an existing DWG, you can use that DWG file as a template in the DWG writer.

Then add the new layer as a feature type in the writer.

Hope this helps.
