Save Points To STL and Measuring Outside Corners -> Built-into TNG?

On Youtube I noticed two features demonstrated and cannot tell if these are readily available in TNG or whether they are something that I need custom G-Code and O code to perform. How do I do the following:

1) Generating STL from probe measurements: https://www.youtube.com/watch?v=QRpyc9iHLls (CNCUSB)

2) Measuring outside corner with probe: https://www.youtube.com/watch?v=jXMB9-SXTRg


Thank you.

What I have found so far to measure the points of a surface ("Save Points To STL").....

In TNG with a probe configured, installed, and ready to measure...

1) Machine -> Measure -> Surface
2) Provide value.
3) Once operation on step #2 is complete....Machine -> Points -> ___________
3b) Notice at the top of the menu Machine -> Points, there is a heading "Count: " that is followed by the number of points measured.
4) Choose to "Save ..." , "Save STL ..." , "Save DXF ..." , or "To Output" (the UI element) .
