Now that the basic organic shape has been created, we're going to make some modifications to it using the proxy. The next two images show what happens when you edit the proxy using convential SketchUp tools, such as the Line tool and Move tool.
An Edge added to the top of the vase creates a new anker where subdivided geometry allows for a modification through the proxy.
Using the Move tool to move the Edge downwards the subdivided mesh updates and creates the curved, organically shaped ridge on the top of the vase.
Using the Crease tool the vase is modeled a stable footing. But this does not need the rigid SketchUp tools like Intersect to create a flat plane. SDS has a Crease tool which allows you to precisely control the
