@unknownuser said: In the reference dialogue box it says reference status embedded. Currently, if you copy a model from one LayOut project and paste it into another LayOut project , the link to the 3D model is not preserved even though the model path displayed in the References area is correct. I dont know if this is what you did but, if so, this may be the reason you see the status as "Embedded". To establish the link, select "Unlink" and then "Relink". I hope this helps CMD

thank you much appreciated

@ely862me said: Edited: just find the pdf splitter and merger That's good because I wouldn't have known the answer as I have never tried to do this (just thought it would work) So you spared me some trial and error playing around now. BTW SU Pro can also export to pdf and that's even vector based (unlike PDFCreator which will export a raster pdf only). (Just trying to look nice at Google )

But it doesn't happen in other sketchup files

thank you
