I have a 3D data set of some buildings in ESRI Shapefile MultiPatch format. The buildings appear in 3D in ArcScene (10.2.1 on Windows 8.1 64bit) and I am able to move, rotate and scale buildings. However when I select a building in an editing session and I go to vertex editing, if I try to edit any of the vertices of my building I am presented with a 'Select a single editable feature to modify' prompt. I am unable to work out why I can't edit at vertex level for this set of buildings.
In addition clicking on the building appears to make it disappears until I select another building and the original building reappears. Anyone have any thoughts about this issue?
