+10I have an aggregate of 4 3D lines which are the outline of a vertical polygon. I want to replace it by a face and can't seem to do that. (In fact it is a wall of a building)
I need LineCombiner to create a polygon which is prerequisite for the FaceReplacer.
As it seems to me LineCombiner cannot handle vertical polygons and so I cannot create vertical faces.
Please proof me wrong or let me know how to solve this.
+19Hi @mhab, the basic idea is: rotate the four lines by 90 degrees around an axis parallel to the wall, build an area from them, then rotate the resulting are by -90 degrees around the same axis to restore the original coordinates. If the wall was parallel to the X axis, this workflow creates the vertical wall.
I think you can expand the idea to apply to walls of any direction.
This is an example. Assuming that the input feature has an aggregate geometry that consists of four lines representing the edges of a vertical wall.

+10Thanks takashi for the elaboration on this problem.
It shows me quite clearly, that there is a functional gap in existing transformers.
LineCombiner is a 2.5D piece of functionality and not really 3D.
Running a Solid through GeometryCoercer (fme_polygon) produces all kinds of polygons also vertical ones.These, on the other hand, could not be created by LineCombiner without quite complex extra work.
Seems a suggestion for a 3DLineCombiner is the next step ;-)
