Draw cross section in 2-D with primitives and boolean operations and then use thicken sheet or sweep surface to create geometry, the gap is going to be tricky probably have to do a polyline and then sweep it. Can't tell what gap size is from picture, or size of anything else for that matter since there is no scale or dimensions. What are you trying to solve for? HFSS may not be your best option.

Dear Reidintransit :thank you for your reply,i use the HFSS to simulate the cable(high speed),but using the 2-D cross section method is not good, the cable's suckout will not happen. in the topic, i see somebody use the 3-D method(see in the attached picture) , the result is better,it is the same with the test result in frequency,but i do not know how to draw the 3-D,I do not know what is the "gap" and "gap size".thank you
