Hi @lalandexavier, I would use a CoordinateExtractor, a FeatureMerger and a VertexCreator. In addition, you can reverse the orientation of resulting lines with the Orientor if necessary.
+10Hi @lalandexavier,
I would use a NeighborFinder transformer and feed the destinations in the Base port and the Centre in the Candidate port. You can set the Id as GroupBy. Next you can add a VertexCreator with 'Insert Point At Index' using the _closest_candidate_x and _closest_candidate_y on index 0.
UPDATE: Using 'Insert Point At Index' and index 0 will cause an error. You can use 'Add Vertex' and if you would like to have the line running from the centre to the destination you could add an Orientor
