particles flowing along wireframe

[NeilAtd]

Hi All,
Pretty new to Tyflow, so please excuse my obvious query.
I am trying to flow particles along the edges of geometry. Most of my current ideas just seem to fall flat. To give you an idea, I have a low poly city and want the particles to flow at random around the wireframe. Any suggestions, would be much appreciated.

Flock operator have an "obstacle", where you can load mesh, and particle will try to avoid it, and go around it.
I even used it once with actors.

Or, if you want them to flow ON geometry, sticked, then use object bind OP.
