Scan Essentials - "Bonus Feature"

Hello to all in the community

I have been using Scan Essentials daily recently and it has become a very important part of my workflow when converting site data to workable models.

Whilst I make use of most features there is one which I still cant get my head around. There is a video online called “3D Modeling in Trimble Scan Essentials for SketchUp” which for reference can be found here: 3D Modeling in Trimble Scan Essentials for SketchUp - YouTube
There is a bonus feature section where it touches on using the freehand tool (12:26) and it shows what appears to be an ‘auto trace’ of the arch. When I have tried to replicate this feature I am not getting the same result. Is this ‘smart’ free hand feature available?

If any one can help me with this it would be greatly appreciated



Can anyone help me with this please? Is it known if this is possible
