Rounded cone

Hello there! I was wondering what´s the best way to create a rounded shape like this WITHOUT using any extension. Anyone has any good idea? :grimacing:

The Follow Me Tool is what you are looking for. From the Help pages

While Follow Me is the ideal tool for this, it is important to understand that you can manipulate shapes by using the underlying hidden geometry that makes up everything.
