Hello.  I have a part from one of our detailers which has an irregular curve (I think parabolic) and I need to develop a 2" thick flange that will follow this contour (and ultimately make this flange into a sheet metal part for flattening).  But first things first, I cannot get the sketch to extrude properly using thin feature.  I started a sketch on the front plane and used "convert entities" from the web plate.  I'm thinking I may need to connect the line segments from point to point and get to a spline but it sketches out strangely if I connect all the points.  I'm wondering what is the best approach here to get this sketch into one entity so that the thin feature will work for extruding, then convert to sheet metal.  I've attached the part.  Screenshots below of sketch.  Thanks in advance!
