When a link travels from a higher layer Component or Port through the boundary edge of a corresponding Component and connects to one of its sub-Components, there will be an Off-Diagram IBD Proxy Port on the frame of the sub-Component's IBD diagram to indicate that the Link passes through it.
Off-Diagram IBD Proxy Ports can be lengthened by clicking on one to activate the layout options and then clicking and dragging either the top or bottom face resizing points.
Resizing the Off-Diagram IBD Proxy Ports can aid in enhancing diagram readability, particularly when there are multiple links traveling through the same Off-Diagram IBD Proxy Port .
