<p>
This partial model provides two frame connectors, access to the world
object and an assert to check that both frame connectors are connected.
Therefore, inherit from this partial model if the two frame connectors are
needed and if the two frame connectors should be connected for a correct model.
</p>
<p>
When dragging \"PartialTwoFrames\", the default size is a factor of two
larger as usual. This partial model is used by the Joint.Assemblies
joint aggregation models.
