Not every type of component or cluster can be directly manipulated in Softimage.
Transforming Components and Clusters
You can transform points, edges, and polygons in 3D space. This is a fundamental part of modeling an object's shape. For more information, see Manipulating Components [Modeling and Deformation Basics].
On curves, you can move knots and isopoints as well as points using the Tweak Curve tool. See Using the Tweak Curve Tool [Surface and Curve Modeling].
In addition, you can adjust sample texture points in the texture editor. For more information, see Working with UVs in the Texture Editor [Texturing].
Deforming Components and Clusters
You can apply deformations to deform points, edges, and polygons in the same way that you apply them to objects. For more information, see Deformations [Modeling and Deformation Basics].
Animating Components and Clusters
You cannot animate component and cluster transformations directly. Instead, you can use a deformer such as a cluster center or volume deformer and animate it, or you can use shape animation. For more information, see the Modeling and Deformation Basics guide or Animating Shapes [Shape Animation].
