Add Close Line Options to PointConnector (LineBuilder)

The PointConnector (LineBuilder in 2017) transforms the resulting line into a polygon automatically if the start and end nodes matched in 2D, but this is annoying when you want to only create line geometry even if the resulting line is closed.

It would be nice if a parameter could be added to the transformer so that the user choose an option how to handle lines closed, including connect Z mode.

Completely agree. You may want to keep a closed line treated as a line and not an area. Surprised no one ever asked before.

In addition, the Creator with this setting generates a polygon with non-closed boundary :-0

 

  • Geometry Source: 3D Coordinate List
  • Coordinate List: 0 0 0 10 0 1 10 10 2 0 10 3 0 0 4
Many users seems to be lenient with traditional functions...

In addition, I noticed the LineBuilder creates a Polygon object if the number of input points is 4 or more and the start and end points locate at the same coordinates (x, y), even though z of them are different. I don't think it's preferable.

This issue popped up for us today. We have driving routes that begin and end at the same location. They're lines but LineBuilder (previously PointConnector) forces them to be polygons. It would be helpful if there was an option to choose the geometry in these cases.

This is a really frustrating. line on line to line builder would be a great solution to avoiding aggregates (because they don't translate into Illustrator or ArcGIS online well for example) but the unique lines keep building into polygons because the lines have the same start and end point.
