How to scale or rotate an object by making a vertex the pivot point

  1. Select the vertexes that you want to scale..etc.
  2. Lastly select the vertex that you want to use as a pivot point.
  3. The last selected vertex should be hightlighted in a different colour. This means that this is the active vertex.
  4. On the top bar, choose the "Active Element" in the "Transform Pivot Point" drop down menu.
  5. Now when you scale, rotate..etc your object, it will use the last selected / active vertex as your pivot point.
