A few years ago I worked on a project with roofs slanted at an angle so that the edges of the roof are not square to the angle of the roof. I was able to extract the actual size of the roof plane as a flattened form so that the run of the roof, the angles of the edges and the number and length of SIPS roof panels could be determined. I cannot remember the exact method I used and cannot repeat the technique in VW 2019. Unfold surface does not work on a roof form as it is not a developed curved form. I have tried extraction, ungrouping then extracting surface, converting to 3D polygons in top view and iso, converting into nurbs then extracting etc etc. A screen shot of the roof is attached
Does anyone know how to extract a roof plane from a roof object in VW 2019 so that the shape reflects the actual run of the roof.
