Is Adapt photographs exist in SketchUp web ?
What is “Adapt photographs”?
If you mean Match Photo, no it’s not.
Yes, that’s Match Photo, and as @colin says, the web versions don’t support that feature. That’s why in my last class I had to go back from SketchUp for Schools (web based) to SketchUp Make 2017 to teach this feature. You can still get Make 2017 if you want to do this.
How can I get SketchUp Make 2017 ?
You can download it from this page:
