On this sheet, it's possible to calculate the exterior walls area and average U-value. In the tutorial, we mainly cover how to measure digital blueprints in PDF format with the program PDF-XChange Viewer, and how to import the measurements to SENIB. Since the tutorial was made, a new software called PDF-XChange Editor has been released which has several great features that "Viewer" lacks. Therefore, the "Editor" is now recommended instead. In the tutorial we cover how to import a settings file to the "Viewer". There are also setting files for the "Editor" but to access the menu “Edit” where the "Import Settings ..." option is available, you must first “Switch to Classic Toolbars" in the top right corner of the "Editor".
