Creating strings

[David.r]

I'm pretty new to Inventor, so feel free to point out if I missed something basic.

I'm making a tower crane for a project and I need to have strings that are attached to the top of the tower and the end of the boom and another that attaches to the top of the tower and the rear boom.  I used the cable and harness tool, but it didn't seem to account for the presences of the cables I made when I ran a stress analysis, which I need to do.  

How would I create a string or an object that would function similarly?

But I would use directed forces rather than try to mesh a cable (string).
