It would be very helpfull, if outlines for multipatch (polygon) features would be drawn in 3D-Scenes in AcrGis-Pro to see the edges of e.g. Buidlings.
Same request and examples exists for ArcgisOnline:
This idea has been marked by Kory Kramer as a Duplicate of Outline color property for non-textured multipatch objects. The original idea is not only for ArcGIS Online - it also carries the Category of ArcGIS Desktop which includes ArcGIS Pro. Please see that idea and up vote. Thank you!
