Need option to place reality mesh as background and ignore depth so all lines are on top of mesh. This is needed for digitizing meshes as when vector is on same plane it may become invisible and sink into mesh. There is option in iTwins web viewer to test against terrain or not so similar option needed here.
Now to work with reality meshes we still need to generate point clouds or export facade as raster so it is easier to work with. It dimishes any advantages of 3D reality meshes.
