Added page for Add Tool
The Add Tool allows the user to add a new object to the simulation.

==Tool Details==

==Location==

The [[Interface#Add|Add]] button is located on the [[Interface#Bottom Bar|bottom bar]]. When clicked, the Add Tool menu will appear, displaying a list of objects that can be added to the simulation, sorted by [[Object Types|object type]], as well as four [[Add Tool#Settings|settings]]: Still, Orbit, Binary, and Launch.

Certain objects can also be added to the simulation with the Launch setting using the numbers 1-8 on the [[Keyboard Controls|keyboard]].

==Settings==

The Add settings determine the initial [[Velocity Vector|velocity]] that the new object will be given when it is added to the simulation.

* Still
** The object will be added with zero initial velocity relative to the [[Simulation Grid]].
* Orbit
** The object will be added on a circular orbit around the object's [[Strongest Attractor|strongest attractor]] in the simulation.
** When an object has been selected from the menu but not yet added to the simulation, the orbit will be displayed.
** If there are no other objects in the simulation, the new object will be added with zero velocity, as in Still.
* Binary
** The object will be added on a circular orbit around the object's strongest attractor in the simulation.
** If Balance Motion is on, the other object's velocity will be changed such that the [[barycenter]] of the two objects will remain stationary as they orbit.
** If there are no other bodies in the simulation, the new body will be added with zero velocity, as in Still.
* Launch
** The object will be launched from the location of the [[camera]] in the direction that the camera is facing.
** If Auto Launch Velocity is on, the launched object will be given a velocity that will put it in orbit around the object's strongest attractor in the simulation.
** If Auto Launch Velocity is off, the user can use the Launch Velocity setting to assign a specific initial velocity.
** If there are no other objects in the simulation, the new object will be launched with a velocity of 10 km/s.
