I have points snapped to line endpoints. I run topologybuilder with assume clean data=y and propogate all attributes=Y. I expect a list attribute _lines{} to be added to the point features i.e. nodes. It is not. There is only something called node_angle{} with no useful line information in it. How do I get the attributes from the connecting lines?

PointonLineOverlayer could set the line attributes on the points.

Another option would be to use the SpatialRelator

SpatialRelator does what it says it will do, unlike TopologyBuilder. A nodal model would've been useful downstream, but, for now, the related records work well enough

 

Do you have the parameter "Propagate all Attributes from Input" set to Yes?

When I use that then I get the street (edge) attributes passed on to the nodes. It is a list attribute, and for some reason the list is called _node_angle - but I do get the attributes.

For example, each node has _node_angle{0}.StreetName and _node_angle{1}.StreetName

Even without that, each node should get an ID number, and each edge gets a _from_node and _to_node attribute that denotes which node IDs it connects to. So you should have a proper nodal model that way too.
