We have been trying to flatten out a non-planer surface, using various techniques. Flattening and Forming seems to be the best, compared to convert to sheetmetal, and Fabric Flat Pattern, but when we water jet the piece, and shape it into the area we are trying to fill, it comes up a bit short. Looking at the length analysis in the tool, it doesn't appear there would be any issues, but I also get an "Output body has self intersections" warning. Also, if I measure an edge of the face I am flattening, it's 25.211", and the equivelant flattened edge is 25.175".
Am I missing something?
