Followed instructions from online resources but can’t get 1:1 scaled model to correctly print from either sketchup or layout. Does anyone have step by step instructions?
How are you sending your file to the printer? From LayOut, it’s best to export to PDF, JPEG, etc and print from there. Also, check you print settings to make sure that ‘Scale to fit page’ is unchecked as for most of us, that gets checked automatically and will shrink the page to ‘fit the margins’.
Is the viewport scene in SketchUp set to parallel projection ?
