A client wants to get a 3D print of their house plan.  Has anyone done this with success?  The printer requires a STL file, which I can do but I would like to know how many layers to turn off and what to leave on before exporting.  (eg. Interior walls, interior doors staircases, etc.).  Should I save a copy of the plan and just clean it up for the export?   The person doing the printing does professional printing for different manufacturers so is quite knowledgable but I would like the best
