Specification Tree

This section provides information about the specification tree associated with a mechanism representation.

The specification tree for a mechanism contains the following items:

  • Product: The product that contains the geometry and engineering connections for the mechanism.
  • Mechanism Representation: The mechanism appears as a representation under the product; it is possible to have multiple mechanism representations for a single product, each using a different subset of engineering connections.
  • Joints: The engineering connections that are enforced in the mechanism.
  • Commands: The degrees of freedom that drive the mechanism simulation.
  • Dressup node: Contains rigid engineering connections that fix together the components that belong to the model to the mechanism's components. Rigid engineering connections appear underneath the Dressup node in the specification tree as long as they connect a product in the mechanism to a product in the model. In other situations, they appear underneath the Joints node.
  • Assembly: A collection of mechanisms that are assembled within a macro mechanism—also referred to as a multilevel mechanism.

The following example represents a typical mechanism specification tree:
