Handle entities control the shape of domains during morphing.

A handle can be associated with any domain, but must be associated with one and only one domain. When a handle associated with a 1D, 2D, 3D, general, or edge domain is moved, it moves the nodes within that domain along with the nodes in any other domain that the handle is touching. A handle associated with the global domain affects only the nodes in that domain. You can make large-scale changes to your model by moving the handles on the global domain and make small-scale changes to your model by moving the handles on local (1D, 2D, 3D, general, and edge) domains. You can also make both large-scale and small-scale changes to your model and have their effects combined in a logical manner.

Handles can also be dependent on other handles, either in the global domain or in local domains. This allows handles to control, but not restrict, the movements of other handles. A handle dependent on another handle inherits the perturbations applied to its parent handle which are added to any perturbations applied to the dependent handle directly. This allows you to set up a hierarchical control system for the handles in the model, such as making three handles which control the positions of three different holes dependent on a handle in the middle of all of them. When the middle handle is moved, the other handles move the same way, which in turn move all of the holes. Moving any one of the dependent handles moves only the hole it controls. You may also make a handle dependent on multiple handles. The dependent handle will be perturbed an amount equal to the average perturbation applied to the parent handles based on distances between them.

Global handles are red and are associated to global domains. Local handles are orange and are associated to local domains. Both global and local handles can have dependent handles which are of varying colors and sizes.

Handles do not have an active or export state.
