I am have a point table of schools and a polyline table of roads (network).
I need to highlight all routes that are within 5km of a school.
Any advice much appreciated.
Thank you.
Hi,
You may find the answer here somewhat useful:

Beyond that, I don't believe FME does "real" route planning, at least not easily with a stand-alone transformer. NetworkTopologyCalculator is probably the closest thing for that.
Cheers,
Jonathan

use neighbourfinder to insert a vertex on the roadlines.
Create a netwerk with the topologybuilder.
Create a from to set. This can be done by unconditionaly merging and removing duplicates.
Then you use shortestpathfinder and select those that are 5km or less. (assuming your network has direction attribute)
