Re: CAD house plans
SPLINES are a component of NURBS surfaces.
i doubt there will be many if any splines contained in a PDF. but there will be ARCs and other elements you do not want to be approximated facets.
i only mention it because it is a better option in many cases. for those that don't want to pay money for illustrator or some other tool. Rhinoceros is free to us for this purpose. (extracting the vectors from a PDF)
i don't know much about sketchup but i do open files from and and save files to it's format for people who do use it to play around with conceptual sketchy stuff from the Rhino.
