Poly-Build Tool (2018.2) isn't using Group ID to split Sequential PolyLines

[dandev1991]

Hi,

I have a text file that has sequential shape points that describe two poly lines, consisting of a shape id (two unique polyline IDs), latitude, longitude, point sequence and distance travelled.

Using the 'create points' tool, I am creating centroids using the longitude and latitude points in the text file above.

Then using the 'poly-build' tool, I am creating a 'sequence polyline' using the centroid as the source field, the shape ID as the group field and the point sequence as the sequence field.

The issue is that the poly-build tool does not seem to be separating (grouping) via the shape id correctly, and I am getting a weird polyline created.

Whereas if I manually split the unique shape ids and then use the polyline field, I get the correct output per shape id.

Any ideas what I am doing wrong?

Hi @dandev1991 

Solution is attached. 

Ultimately, it comes down to the sort order of your Sequence field since the "shape_pt_sequence" is a V_STRING, the order was alphabetic instead of numeric. By changing the field to a numeric data type (in this case DOUBLE) and then running the workflow, it functions as expected.
