How do I model cable for a cable-stayed bridge?

Hello SolidWorks community. I've only been using the software for this semester, so I'm not as well-versed as I need to be to complete my course's Engineering Design Problem. My instructor recommended modeling cables as thin tubes, but I don't know how to attach them to the pier of the bridge. Running a simulation shows that the way I'm doing it now is no good.

 

To get the current product, I did a 3D sketch of each half of the deck of the bridge and the pier, extruded and filleted to the size I want, and mated them in assembly. Then, I 3D sketched each of the cables as lines in the assembly, copied a line, pasted in a part, applied a material and Weldments profile, and pasted them back to the assembly. I deleted that line, mated the ends to the bridge, and repeated.

 

Since this is a preliminary design with few calculations as to the size of the deck and supports, the ability to adjust that after running the simulation would also be super useful.

 

Any help is greatly appreciated!

 

 

(I had to take out the study in order to meet the file size requirements. I modeled the supports of the pier and the closer end of the bridge as rollers and the other end of the bridge as pinned. The total force on the deck is 11007.40 kN.)
