Best Lenovo laptop series for Architectual/Interior/3D Graphic Design with the touchscreen/stylus for Sketchup 3D.

Hi

I am learning to use Sketchup/V-Ray software for architecture/interior design for my business.   I see that Lenovo has Workstations with powerful processors but I really need a portable laptop with a large screen 16" min. preferred for customer presentations.

The gaming Legion laptops seems to be the most powerful with graphic accelerators are attractive, as well as the Yoga series with slim and lightweight profile with display flexibility is great for presentations.

Any recommendations on what series and type Intel/AMD processor will be appreciated.   

Thanks!
