However when I'm working with ArcGIS Pro, I can't find out how to do this. ArcGIS Pro works perfectly for visualizing 3D and it has many 3D tools and options, but the export of 3D features I haven't found (yet).
How do I export a 3D map from ArcGIS Pro?
(File types *.wrl, *.u3d or *.prc are all fine)
