Step 3/6: Raise the Roof

This step is where the magic occurs. Pull the first open central vertex together. This vertex is indicated by a square around it in diagram below. When you do this, the vertex on the roof of the dome (vertex A in diagram) will rise off the ground. You will need to drag all other vertices around when this happens. After this step, every connection of a vertex will cause the dome to rise and change shape.
