Topics covered in that lesson:

Manipulating with polygons in Sculpt mode:

  1. Selection (something like Autocad rectangular selection, dragging from left to right, from right to left)
  2. Scaling polygons, rotating polygons
  3. Working with symmetry

Conclusion: it’s nice quick introducing to sculpting mode in fusion 360. Instructor showing his workflow to sculpt some glass vase, nice demo covered how to make polygon manipulating and working with symmetry.

Actually, pretty nice lesson. Workflow a bit different from polygonal modeling. Worth take a look for completely newbees.
