Graphic3d_CStructure and OpenGl_Structure do not store structure aspects anymore. Graphic3d_Structure, Prs3d_Presentation - structure aspect methods have been removed. AIS_InteractiveObject::SetAspect() - globalChange argument has been removed. Undocumented test methods V3d::DrawSphere(), ::SetPlane(), ::PickGrid() have been removed.
