Question

What does this mean in detail? "A spiral or curve geom has been dropped"

O

I have a LandXML file that contains clothoids, i.e. spiral geometries. When I inspect the file, I get warnings like this:

The Coord child element is not currently supported. FME Currently only supports Chain, Line, and IrregularLine. A Spiral or Curve geometry has been dropped

What does "dropped" actually mean?

The geometries are in fact aggregates of straight line segments and curves (road and rail designs). Some are simple (radial) curves, and some are clothoids (spirals).

There seem to be small gaps in the geometries in the data inspector viewer.

Not familiar with LandXML myself, but "dropped" seems to indicate those objects (or rather those elements) are not processed. That would explain the small gaps you mention.

At the User Conference it was announced that clothoid support is coming, I'm not sure whether it's in beta yet though.

Hi @ottadini & @redgeographics, the latest FME 2018.0 betas now support clothoids as a geometry type. You can even create them using the Creator.
