Transfer Area using at automated yard.

Hi all
I try to build up automated yard (vertical type block). I used transfer area object to transfer container between vehicle and Gantry crane at in front of block. but vehicle looks go inside block. so I am curious how to use a transfer area node. I just linked each vehicle with transfer area node and a transfer area node linked block as well. I still assigned gantry crane each block and assumed the gantry crane same as RMGC.

I am curious what is my wrong assumption..

It would be easier to tell you what is wrong in your model if you would post it.

Attached is a functional sample model that shows an end-loaded block using a transfer area.

thank you so much!
