Adding a new object type is pretty simple in Element. Click the ADD '+' button on the Homepage. The add menu will open:
Recent – Displays recent objects you've created or opened.
Options – Displays all object features in Element
Search – Search for object types here.
Selecting the object brings up it's respective form (below):
Forms enable you to capture parameters for that object:
Fields – This is where you enter details for your object.
Cancel – Exits the form without saving any changes
Save – Saves the form and opens the object Carousel
Save (+) – Saves the form and opens another Add New form. That means you can keep adding new objects one after the other.
