can we use GAP port for cpw structures in IE3D

hello everyone,

Please can anyone answer these questions and help me out.
Can I use gap port for cpw in IE3D? What is the difference between GAP port and CPW port in IE3D. If i can use gap port, how can i use it practically while fabricating the device?

Thanks in advance
