DAE/KMZ mesh/model pieces may show up in the wrong place. This is because Adobe does not create meshes for polygon types like Lines and Points.  In addition, because the mesh hierarchy is not accurate, transformations may not be in the right place. Unfortunately, as Adobe does not support lines and points in their renderer, Adobe currently has no way to resolve this issue. You can read more about this on the Adobe website at the link below:
