I think Andreas used this utility to make the eGPU drive the external display:

https://gfx.io/

SketchUp showing its windows on that display should then be using the eGPU.

Wow Andreas,
I am VERY interested in how you accomplished this reroute to an external GPU (eGPU in the trade)!
And, as MichaelSaggers immediately asked:
“So my question is How do you tell it to use the eGPU? with the MacBook Pro rather than the Internal GPU? Or does it do it automatically when an External Screen is plugged into the eGPU?”
I’m on an iMac and would LOVE to know HOW to do this! My research has concluded there was no way to bypass my internal GPU for any SU or LO processing …
Please share your path and method!
Thanks!

Michael,

As soon as you plugin the extern monitor in the eGPU it just works.
The discrete graphics card in the MBP (for me a Vega 20) then runs the internal monitor of the MBP. (Shows up in the info of my MBP).
With some programs you can choose (info button of the app) which card to use.

There is also an app gfxCardstatus.app, where you, allegedly, can force to use the eGPU. See in this thread above (Colin, #11). Although with this app I have still to check if there is a choice between my discrete card in my MBP or the one in the eGPU. Or that it makes any difference with or without an external monitor.

I will post this tomorrow when I have had time to look at the app.

See my reply below how it works.

Apple gives an explanation also on their support pages:

I hope this will answer your questions,

Thanks much AndreasAM,
I appreciate your helpful information … I have pinged Adam on the SU LayOut team for his opinion/confirmation that this approach will indeed work.
Hopefully this ability to bring some serious horsepower to the Mac graphics processing (via eGPU) when running LayOut will help the sluggish performance!

Thanks for your reply and thanks for letting me know about the website. It’s fixed now so you can check out some of our studio design work.
