Hi hangten1 My steps... View Top Camera ->Parallel Projection Zoom Extents File -> Print Preview Try with my settings. Scale 1:5 will fit on A4 page. Scale 1:1 will need 995.3mm x 532.8mm page or you can print few views on few pages to get the truss in desired scale. PS. I have PDF Creator installed to test any printing scale and page format available. [image: QhcP_20130413-SUFPrint.jpg] bridge1_beginner.skp bridge1_beginner.pdf
