As a developer i need access to the modellines that constitutes the sketchlines for objects like Floors/Walls/Roofs etc.
As of now these sketclines are contained in a Sketch.
I need the stable reference of the Sketch element (or the ModelLines themselfes) to reflect its subordinate relationship to the element being sketched. So the first part of a Sketch stablereference could be the UniqueId of a Floor, followed by its own Id.
