Description
Dissolves a mechanical component inserted in the current drawing by selecting all entities to dissolve manually.
Note: Only components at the first level, directly branching from the root component, in the mechanical hierarchy can be dissolved. To dissolve a component at a lower level, its parent component(s) must be dissolved first.
All subcomponents of a dissolved component are moved up one level in the mechanical hierarchy.
Dissolving a component insert does not affect the source drawing of the component.
The selection set must contain component inserts only. If not, a message displays in the Command line: "No components selected."
