I run into a problem when using the clipper transformer.
As "clipper" I use a .shp file with a clip area.
As "Clippee" I use a file geodatabase with 3D data.
When a polygon is cut it is logical that at the edges of the cut area new coordinates are be created. This must be done in such a way that the polygon is still closed in 3D. Here it goes "wrong" within FME. On the edges of the clip area FME created a new coordinate, with z-value 0.0. As a result, there are multiple coordinates to lie on each other with a different z-value.
See attached picture as example. In this example, starting coordinates 0 has an incorrect z-value whereby the polygon cannot be closed in 3D. Coordinate 1 also has an incorrect Z-value. In addition, this coordinate is redundant (but that is less relevant).
The consequence of these z-values are easily visible in ArcScene. The overpass is cut and get new coordinates with z-value 0.0. The overpass will go through secondary roads.
I would like to understand the cause of this issue. Do you have any idea how I can eliminate this issue?
With kind regards,
René
