AtLeastOneMCX

This check verifies whether at least one constraint is driving the position of a CATProduct instance. If not, the element is considered as incorrect.

Context

In an assembly, you can define the relative position of components using the following constraints: contact, offset, coincidence, and angle constraints. Constraints are used to restrict motion along one or several of the six degrees of freedom.

You need to create a least one constraint to specify the position of the component. If a CATProduct instance is constrained by at least one MCX, a Connections of node appears under the CATProduct instance.

In this example, the part in a green frame includes at least one MCX, and the part in a red frame is not constrained.

To determine a specific position for a component, you can either:

  • Create and apply a position constraint on all six degrees of freedom.
  • Fix the component.

Tip: You can also position components according to the assembly origin. In this case, position constraints are not required.
