How do you take raw scan data and get it to a mesh good enough to start modeling from? Do you need to reduce the size first?
That's a Geomagic Design X specialty. wide range of point cloud processing tools and many options for converting multiple scans to a merged mesh. You can model with a full resolution scan data set, but depending on your system resources or personal preference you might be a little more efficient if you spend a little time upfront to optimize or decimate the model.
This isn't really scan data, looks like a completed mesh. Could you do a tutorial with a raw scan data file?
They use Creaform Handy-scan 700 and the raw scan data is an STL mesh like what is shown in the video here. You can choose when scanning if you want points or a mesh in VX Elements
