The middle line in road construction is often represented in LandXML and it's proposed vertical alignment for the profile is save in the ProfAlign element. Right now FME can't interpret the ProfAlign element which means that the data is in 2D without the vertical alignment.

I am actually developing a sort of custom transformer that can read the vertical dimension of landxml.
I will keep you posted!
Anyway, a great idea!
+4I also need to read the vertical alignment from the landxml files. @jneujens, did you succesfully build a custom tranformer for this?
krisvesweco Yes, glad someone might use parts of that work. Since the amount of LandXML files we could test on were limited, the workspace is not 'production proof' but I'm always happy to dig that workspace up and see if we can make it work.
+4Sounds great! I have quite a few files to test with. I will be happy to share any improvements if I can make any.
Always welcome to send them to over email. I will try to get you a clean workspace over the weekend. :)
+6The ProfAlign element for the PVI in LandXML is now supported in the latest FME 2020 beta found here: https://www.safe.com/support/downloads/#beta
+11Thank's @trentatsafe Will you update this idea with the status "In Beta" then?
+4FME now reads ProfAlign
However the reader does not combine the vertical and horizontal alignment to a 3D line/path. It's possible todo this yourself (I just did.) but it would be great if that was an option of the reader. Quite a few transformers are needed to do this "manually"
Some other improvements of the reader would also be nice. For example the landxml_landxml_type attribute is always Alignment but for the profile lines it should really be ProfAlign. Also there need to be an attribute called ProfileName or similar which fetches the name of the profile.
