How to get the elevation on the polygon?

This is my modell and everything is good intill Generalizer

Is there som better way to get the elevation on each polygon? This picture is from the Generalizer and it is pretty nice just miss the elevation. Elevation is now 0.

Is there an elevation on the features prior to the Generalizer? If so, you can try using the ElevationExtractor to get the elevation values into an attribute.

Hello I tried the Elevation Extractor so my new aet up is like this:

The other transformer like CoordinateExtraktor, AttributeCreator and 3Dforcer I removed. I am running the FME now so are awaiting the reult. The NumericRasterizer I set to 0.02 that is maximum resolution, this make the time it use on the process longer but I get mor elevation information and hopfully it can draw mor acurate polyline.

All of the transformer are doing as expected just I am not sure how to set up the ElevationExtractor. It is getting the elevation byt they are not taken on to the next transformer, so the Z value are set to 0.

When FME is ready I can show the log

Hello this is standing in the log:

"Shapefile Writer: Feature type 'LAS' recieved a geometry that was modified to fit the selected dimensions of the output: Z coordinates have been set to default of 0. If this is unexpected, check the settings of the writer"

There har 11 warnings:

I tryed to use the lasfile as source but it says it is missing the lasfile. When importing the file to CC program it says somthing missing and I get one polygon.

Set the Output Dimension of the shape file to 3D+Measures

Thanks this I hawe got tip on previous, so there is somthing else I am doing wrong, here is my nev setup:

I wonder iv elevation should be before disolver, I tryed this too but dont change anything.

I run this now because I get up after <RasterToPolygoneCoercer> that Z values are set to 0, so then I try to get them back, create an attribute for so and only stand again with polygon around the building.

Finely I got a bit closer but it is not perfekt and it is missing the rest of the polygone.

Are the other setting I can use?

Hello I finely figure oute the problem and the moddel ar adjusted again by putting the 3Dforce after the elevation ekstraktor and it this was the solotion. I have som problem in my lasfile withe noise but I am going too use the dont hull and areal calulator to remowe this noise. Hope that wil do it. Then Thanks for the help It realy get one more step closer.

Here is the result so far by the way:
