Sadly it is not functional. I've yet to figure out how to do that, though I will be trying over time.

In SolidWorks there is a Chain/Belt Tool. I used that, then copied the sketch and put it in its own part file. I then dropped the part files for the two different types of links. (Inner link and outer link) I constrained them to the sketch line. I then used a "Curve Driven Pattern" to pattern them around the sketch curve. (Make sure to make them tangent, otherwise they won't curve round the bend) I then "deformed" the sketch adding arcs in order to get the correct amount of links to fit right, and added the half link to save space. It wasn't an "exact" science, but it would definitely tell you how make chain links you need. No more guessing.

I then saved it as a part, and just constrained it to the sprockets inside the assembly.

I used SolidWorks 2011/12 Student Version as supplied by Oklahoma Christian University to all of their students.
