How are drawings protected from alterations?
Live or printable files are never posted to the Webb. What viewers look at on screen are non-alterable, low-resolution thumbnail images. Even the printable files, stored on the local reprographer’s servers, are non-alterable. Files are saved as 400 dpi Class 4 TIFF images, meaning that all vector data (line and layer information typically used in programs like AutoCAD, Microstation, ArchiCAD and others) are unavailable for manipulation.
