Hi,
Just like what is asked in subject. My user is considering to view voxel layers in ArcGIS Portal to prevent any possible data change from other viewers.
Hey there Kristie,
I have done some research on the inclusion of voxel layers in ArcGIS Enterprise and can confirm that it is unsupported at this time. I would suggest that your user log an enhancement request / log an idea to request this functionality.
This will be amazing!
