What do you call the process of "mapping a point cloud"

I've heard a few names for taking a point cloud and drawing linework and adding feature points for a topographic map. I've heard of 3D modeling, pulling data from scan, mining data from scan, office mapping, etc. What do you all call this? Jokes/humor is accepted.

Feature extraction (sometimes with the "automated" qualifier) is the technical term that we use in contracts and reporting.

Virtual surveying is what I call it informally. Zoom around the cloud and pick out what you want.

To continue from Rover83

I was using points from feature extraction to draft 3D lines for wire model instead of the software picked because it wasn't doing what we wanted for the representation we needed. WEIRD surfaces and features.

Definitely depends on the registration and quality of the point cloud and density too.

FREEHAND 3D drafting 

I accidentally created THRAC.  

I'm confident this won't become similar.
