SampleLineVertex.Location failure

Jeff_M — Fri, 26 Jun 2015 20:28:58 GMT

What would cause the setting of a vertex location to fail with "Location should be set to new location on the same side of alignment as SampleLineVertex." when the supplied point is clearly on the same side of the alignment as the vertex? I have the command draw a line between the original vertex location and the desired new location. This all seems okay, except the API thinks otherwise. The following video demonstrates that this does work for some samplelines, but not for others.

OK, after further tests with other alignments, I now know what is going on. When the road loops around, and the sample line extended can hit the alignment other than at the sample line's insertion (center) point, the API determines the side of the new location from that other intersection point, and not from the actual sample line's station. This should be considered a bug, I believe.

@augusto.goncalves - can you confirm this? Ask the dev team to correct it?

Jeff, I'll review and escalate this. Thanks!
