Rhino plugin to measure distances and angles?

Intro info:

PBS NOVA Cold Case JFK: Laser Scanning and Models

The gentleman that you see in the video above is using the Rhino plugin seen below.

Do you folks recognize it?

I would like to develop a tool similar to that one, but web based and specific for the study of the Dealey Plaza incident.

If you know of similar tools for other apps, I am also interested.

I think it might be a built-in tools.

I’m sorry if I misunderstood your question.
