Hi Chad...
- CoordinateCounter, then
- Tester - set it to _coordcount = 2
- FAILED = allow features to continue to SDF output
- PASSED = Add a LengthCalculator, then
- Followed by an ExpressionEvaluator set to @Value(_length)/2, then
- A Densifier set to densify with an Interval based on the _result attribute from your ExpressionEvaluator.
That process adds an extra node to your 2 noded lines, in the middle to make them have 3 nodes! Now you have all polylines... Drop a GeometryOGCValidator on the end to make sure you have all valid geometry...
Hope that works for you.
