since updating from 2014 to 2015 Sketch Up Pro cannot print model as pdf
you will find the 2D PDF export of SU Pro (not Make) at: “File > Export > 2D Graphic”.
the export settings dialog of the selected format can be found by clicking the “Options…” button in the dialog above.
thank you that helped
To print to PDF you need to have installed a PDF printer (Adobe Acrobat or one of the zillion freeware/shareware alternatives).
Pro users can export to EPS or PDF via the File menu>Export>2D Graphic, but what is exported is a pure vector image with no material textures, Sketchy Edges styles, fog or shadows. These are all raster image-based effects.
