PRIMITIVE
PROPERTY
This will help you create a GEAR PSet. This is a custom property in which you can store it’s own layout and logic. This way you can dynamically generate custom properties with a custom layout and have them persisting even after reloading the scene. It is basically an evolution of the Custom Property With Persistent Layout by Daniele Niero as describe in this xsi blog post. (Thanks to him !), but the GEAR version is written in Python and can also store the logic of the PPG.

New Parameter Set	how to use it : select an object. Will create a new Parameter Set on selected object.
Debug Parameter Set	how to use it : select a GEAR PSet. To force the property to display the layout and logic code.

ICON
These are all the rigging icons available. Even if curves are slower to display than nulls and a lot of people recommend to use null as controlers inside Softimage. We decided to go with curves as we can shape them exactly the way we want. We feel it is important for animators to have clear and easy to grab controlers. Note that inside the gear rigging system you can replace any curve controler with a null icon.

MODELING

Match geometry	how to use it : select the geometry, pick session is asking for reference. Match the geometry points position to another. Geometry can be match in local or global coordinates and a blend is available to add more or less influence.

RIGGING
TOOLS

Get Distance	how to use it : select two or more objects. Log the distance between selected objects.
Draw Axis	how to use it : select objects. Create 3 curves children of the selected object representing the x, y and z axis. Useful to check the orientation of an object.
Add Null Parent	how to use it : select object. Create a null parent of selection with the same transform.
Add Null Child	how to use it : select object. Create a null child of selection with the same transform.

TRANSFORM
Work exactly like the Softimage native Match transform, but the native one sometimes doesn’t work.
Also this one can match Translate and Rotation only or Scaling and Rotation...

SOLVERS
Help you to apply one of the custom solvers. There is only a few available right now. The rest of them are only accessible through scripting.

Create Spline Kine	how to use it : select objects.
Create Roll Spline Kine	how to use it : select objects

RENAMER
A custom property that helps you to rename your objects, chains...

CHARACTER
This is the menu for the GEAR’s Rigging System. Please refers to the video on the Vimeo GEAR’s channel to get more information about it. - Rig fix : sample curve op wasn't working because of wrong operator name

Build From Selection	how to use it : select a guide or part of a guide. Generate a rig from selected guide.
Build From File	how to use it : file browser prompt to pick a file. Generate a rig from a given file (xml definition of a guide).
Guide Tools	how to use it : ui is prompt to provide tools. Tool set to create rig guide.
Update Guide	how to use it : select a guide model. Used to update the guide if one of the component need new settings. Your existing guide will be prefixed with “_old” and a new one will be available in the scene. Not that it is not necessary to update a guide that just been imported from xml definition as guide are automatically updated on load.
Import Guide	how to use it : file browser prompt to pick a file. Import guide in the scene from a file (xml definition of a guide).
Export Guide	how to use it : file browser prompt to pick a file. Export guide to xml.
