When loading a component into another drawing the faces of the component get disassociated from the line work in 2017
What? Can you upload an example that shows this?
Like DaveR, I don’t see the same issue as you are getting. I wonder if it is a graphics card/driver problem?
I believe you are correct. I fired it up on my surface and it is fine.
Try updating your Quadro driver. If your machine also has an Intel display chip check in the Nvidia 3D application settings that SketchUp is set to use the Quadro (In a Quadro driver the setting might be “OpenGL rendering GPU”, and it should be pointing directly to the Quadro, automatic selection favours the Intel chip).
