How to share 3d (Z) polylines on AGOL or Portal?

[AlessandroValra]

I was trying to load 3d lines to AGOL from Pro 1.4 with some problems. Using the "Share as Web Scene" in a scene with two linear layers, I shared the web scene and the related feature layers to my AGOL. Opening the scene in AGOL, I discovered that only some layers are present, while others are just listed but empty (no geometries nor rows in the attribute table).

So, as I found documentations on sharing 3d points and multipatch, but not 3d lines (and polygons), except a page saying that "it is possible to do it", I'd be happy if someone could provide a useful link, or a brief explanation on how to share 3d lines to AGOL (or Portal). Many thanks in advance!

The layer that is empty does it have lines that are completely vertical (same xy diferent z values).

[AlessandroValra]

Exactly! This was my guess that having geometries with ShapeLength = 0 (only vertical length) is the problem. Can you confirm this? Am I forced to change the xy a bit or is there any workaround? Also, not all geometries are like this (it's a layer representing stairs and elevators, and only the elevators have same xy nodes). Thanks!

UPDATE

I removed the elevators and now I can see the geometries. Again, is there something I can do except moving the xy coordinates (it does not make much sense for elevators)? Thanks again for pointing me to the right directions for solving the problem.

This is a current limitation with the data going into SQLAzure and pretty much being rejected. A workaround could be the elevator lines be converted to multipatch and publishing them in a scene layer package or you can use the beta feature where you can publish a scene layer from a feature layer (multipatch or points) for the time being while we continue to look for a solution for this issue.

[AlessandroValra]

Ok thanks. I think I will try to recreate my elevators as multipatch as a workaround then until the vertical lines will become supported.

Let me know if you have another question and I will try to remember to update this thread when this issue has been fixed.

Hi Russell,

Did this issue get resolved? I have 3D polylines and I want to publish it as scene layer, what's the best way to go about it?

[RussRoberts]

You will still have to convert the features to multipatch to keep the vertical lines that share the same xy with different z values.

Problem: Z and M values are not returned for some features in a feature layer hosted in ArcGIS Onlin... 

You can use this tool:

hmm, it keeps failing and crashing Arcmap. I have 3D polylines projected to web mercator and I tried creating 1 inch buffer using the buffer 3D tool. Am I missing anything ? any thoughts?
