# IoJoint

Back to '[**Basics On How To Create Your Own Node**](https://ariserigging.com/docs/how-to-create-your-own-node/the-basics-on-how-to-create-your-own-node/)'

Arise creates the Maya joints we declared in the *joints_creation()* method, during the 'Build' process.
You can access those joints in the *rig_creation()* method by calling on your class variables: *self.my_joint.****pointer***
Which will return an object called IoJoint.

The IoJoint object can be used in 2 ways: 
One way is to simply use it with the Maya **cmds** library which usually takes the string names of Maya elements as its first flag.
For example: *cmds.xform(self.my_joint.**pointer**, q=True, matrix=True)*
This works because the IoJoint __repr__ method had been reimplemented to return the joint long name.

The other way is to use the IoJoint built-in methods described in this document.

A major benefit of using IoJoint is that internally IoJoint tracks the joint using its UUID, which avoids a lot of problems compared to simply storing the joint string name.

As IoJoint is a subclass of [**IoTransform**](https://ariserigging.com/docs/how-to-create-your-own-node/iotransform/), it has all the methods available in [**IoTransform**](https://ariserigging.com/docs/how-to-create-your-own-node/iotransform/).

IoJoint methods:

**set_radius(value)** 
Change the joint radius
Arguments:

- value {float or int} -- The new radius of the joint

**add_joint_orient(rotate_x=True, rotate_y=True, rotate_z=True)**
Transfer the values of the joint orient XYZ attributes to the joint rotation XYZ attributes.
Keyword Arguments:

- rotate_x {bool} -- True to transfer jointOrientX to rotateX (default: {True})
- rotate_y {bool} -- True to transfer jointOrientY to rotateY (default: {True})
- rotate_z {bool} -- True to transfer jointOrientZ to rotateZ (default: {True})

**zero_joint_orient()**
Zero the values of the joint orient attributes.
