Can it do automatic from a scanned image/PDF/DWG file?
The software allows you to import a scanned (raster) image and to “trace” or digitise over the top (even with contrained angles and lengths) to generate the roof shape. However, the accuracy of this method is going to be constrained to the accuracy of the original image. We also have tools to calibrate the image to the appropriate scale and size (1:1) but again it is still relying on the accuracy of the user clicking rather than typing in actual dimensions.
