I work with the 3D mapping tool Drone Deploy. Images are exported directly to Sketchfab. One of my models, https://sketchfab.com/models/6b72812f494b48288a7ef2c5d12a66e8
would benefit greatly with an edited boundary, eliminating half houses and poorly rendered areas outside the main interest.
I'd like to also add labels, marking the various entrances to the buildings. Is this possible to do direct in Sketchfab?
