Hi Richard, Just wanted to update with this.
It seems I may have over thought the original question I asked.
In the end to count the possible number of utility poles I would need I simply did the following...
1. I created points on line intersects
2. I then placed points on a lines at given intervals depending on the line length.
Obviously doing this meant that the poles were on street centre lines so their position wasn't accurate but it gave me an idea of the number of poles I I may need.
However I wasn't able to get 12 properties per pole but in the end this didn't really matter. But to show the properties connected to poles I just created spider diagrams.
Thanks again.
