The Points Window can be opened by selecting Points... from the Geometry menu. The Points Window allows you to rename points and assign points to a bone joint. To create points, see the Create Point tool.
The points combo box lists all the points in the model. Selecting a point in the combo box will cause that point to be selected (all other points will be unselected). After selecting a point you can rename it, delete it, or assign it to a bone joint.
The Rename button allows you to rename a point. Point names do not have to be unique.
The Delete button deletes a point.
The Bone Joint drop-down box lists all bone joints in the model. Select a bone joint to assign the point to the specified joint. Note that using the Influences Propertes Panel is more flexible than the Points Window when assigning bone joints.
