Two side Nested port in SYSML ibd (internal block diagram)

[maziar1]

Hi

i try for test create ibd  diagram with two block or property .

also i read  https://sparxsystems.com/enterprise_architect_user_guide/14.0/model_domains/nested_ports_in_sysml_1_3.html

but

1. But seem upper link way to create nested port not usefully if both side of connector need nested port !!

2. I no understand why must use this complex way to create simple nested port (port in port) .  why we can not easily put one port in other port the same as many other tools .... !!!
