Hello,
How can I add the elevation as 3rd dimension to existing segment?
I have the elevation values for the starting and ending points of each segment.
Thanks

Hi @arthy, take a look at the 3DInterpolator transformer.
@takashi
Let's say I have a segment with boundary A(x1,y1,0) and B(x2,y2,0) and I have the information z1 and z2.
How to proceed to modify the geometry of that segment such that the boundary will be A(x1,y1,z1) and B(x2,y2,z2). For now, I don't rellay want to interpolate the 3rd dimension between A and B.
Hi @arthy, take a look at the 3DInterpolator transformer.
Is the geometry type of the segment feature is line?
Does the segment feature have the elevation information as its attributes?

Hi @arthy,
I'd avice you to do as follows:
- assign unique IDs to your segments by the Counter,
- then chop them to vertices by a Chopper,
- assign IDs to every vertex by a Counter and
- then adjust height of your vertices accordingly. For example you could obtain Z-position of your control points and transfer them to your segment vertices by a NeighborFinder.
- Once the Z-Attribute has been transferred push the vertex into this position by help of 3DForcer and
- than use a Sorter to rearrange correct order of your data.
- By help of PointConnector and separation attribute of your segmentID you will receive the initial features but now with 3D coordinates.
Hope this helps!

No.

Thanks for your answer.
I finally used a pythoncaller which give the desired solution in a few lines.
coord = feature.getAllCoordinates()
n=len(coord)
coord[0]=(coord[0][0],coord[0][1],z1)
coord[n-1]=(coord[n-1][0],coord[n-1][1],z2)
Hi @arthy, take a look at the 3DInterpolator transformer.
Two pairs of the CoordinateExtractor (Mode: Specify Coordinate) and the VertexCreator (Mode: Replace Point At Index) do the trick, after you merged z1 and z2 to the segment feature.

As I explained to @whkarto above, I used a python caller to do that.
It was more simple.
Thanks for your help
