Summary

Adds a new object to the frontmost simulation.

Description

When you select this command, a small dialog will first be displayed inviting you to choose a parent for the new object. You can either select no parent, in which case you will be creating a new independent object, or you can select an existing object to be the parent, in which case you will be creating a new child object in orbit around the chosen parent.

When you select no parent, the object editor will be displayed showing the twelve independent fields that describe a default new independent object. This is an object that is set up independently of other objects using absolute elements, rather than relative to a parent object using orbital elements. These fields are displayed in two boxes containing six fields each, and the upper fields will be the physical elements and the lower fields will be the absolute elements. You can edit these fields and then choose OK to accept your edits, after which each of the frontmost simulation's open windows will be updated to reflect the change.

When you select an existing object to be the parent, the object editor will be displayed showing the twelve independent fields that describe a default new child object. This is an object that is set up relative to a parent object using orbital elements, rather than independently of other objects using absolute elements. These fields are displayed in two boxes containing six fields each, and the upper fields will be the physical elements and the lower fields will be the orbital elements. You can edit these fields and then choose OK to accept your edits, after which each of the frontmost simulation's open windows will be updated to reflect the change.

There is a Details >> icon (Show more choices icon on a Mac) in the top left corner of the object editor that you can click on to display all the new object's data elements instead of just the twelve independent ones. This icon will also change to a Details << icon (Show fewer choices icon on a Mac) that you can click on to display just the twelve independent fields again. When the object editor is displaying all the new child object's data elements, some of them will be non-editable. Also, because many of the fields are dependent upon each other, editing one may cause the automatic update of others to maintain consistency.
