Selecting Feature in Web Scene Layer Shows Selection Outline Underground

GBacon — Thu, 03 Aug 2023 14:07:07 GMT

In both local and global web scenes, the selection of a building feature results in an underground outline of the feature that is distracting to the user. Is there a way to prevent this?

Selection highlight has a "shine-through" effect to make it visible even if (partially) occluded. This is by design.

In your specific case, it looks like the building has a single bottom plane underground. Can you check if this is the case (e.g. by hiding terrain/ground, or lifting up buildings with elevation offset)? If that's the case then the highlighting behavior would be as expected.

If there isn't a bottom plane I cannot see an obvious other issue just from the picture. Would it be possible to share this scene (or a reduced subset that shows the problem) publicly so we can have a look? So far we were not able to reproduce this case, and we might need to have a closer look at the actual scene / actual data to be able to track this down further.

Thanks, Andreas.

After hiding the Lidar Point Cloud, and making ground transparent (in basemap widget) we can see that all buildings indeed have an underground "footprint" polygon (or rather a polygon outline).
All parts of a feature get selected and highlighted, i.e. the behavior you see is expected. There is no option to selectively control the highlighting within a feature.

Can you recreate the features (the Building SceneLayer) to not include the underground footprint part?

How do I do that? Is it during the publishing process in ArcGIS Pro? I've never seen this behavior before. I thought maybe you meant there was an accompanying feature layer causing this, but these are the only items created when I published the multipatch:

Not a Pro expert, but AFAIK the publishing process will not add these, they must be there before publishing already.
Check data in Pro before publishing, pretty sure they show up there as well (though might not be underground). My assumption is your data contains these footprints. Or they get added somehow in the creation process.

The building outlines do show up underground in Pro.

I resaved the scene above to highlight the building shown below as it does not cast an outline, web scene or Pro scene, when selected. This building was created manually in Pro using editing tools while all others were created using the 3D Basemap Solution. This building was added to the multipatch output from the solution and then published. Why does that make it behave differently in a web scene and Pro?

This looks like a difference in the output of using the solution tools vs. manual generation. The footprints look to be apart of the multipatches. The coloring and styling of the footprints matches the building type color value, if you enable edges the footprints also get the edges at the same time. I would ask this question in the solutions forum.

Thanks, Russ.

I opened a support ticket and will try the solutions forum if that doesn't answer my question.

Hi,

How are the buildings symbolized in Pro? Are they building footprints with a procedural rule? If so, then turn off the solid stroke renderer before creating multipatches:

Thanks, Gert. Your presentations at UC are always very informative!

If the 3D Basemap's tool output symbolizes the buildings with a procedural rule, then that is probably what happened. I didn't check that a couple months back and don't remember exactly what the output looked like. Is there a .rpk file I could go back and use in Pro to symbolize the buildings without the stroke and republish? Maybe it came with the solution download(?)

Here is a material fill I was hoping to use but the problem remains. Now I know that my replacing the building in the center with my own model somehow didn't pick up the stroke and that is why is has no outline.

I found the project and saw the two layers in question:

Geoprocessing history says I ran Layer to 3D Feature Class on Buildings_Extract_Roof_Form to create Buildings2018LiDAR multipatch.

I see that the Publish Buildings Layer task converts multipatch to feature class; I don't know why I didn't run that instead. Would that have modified the procedural symbology to avoid the outline issue?

Re: Selecting Feature in Web Scene Layer Shows Selection Outline Underground

GBacon — Thu, 10 Aug 2023 18:07:01 GMT

I turned off the stroke layer on my procedural rule symbology (output from solution task) and then converted to multipatch using the Publish Buildings Layer task. If possible, it might be good to have the task add a step for modifying the symbology before converting to multipatch.

The published features do not show the underground selection outline anymore. Thank you for your help.
