I have 6 hours into this thing at least...importing, exporting, fitting splines, trying everything I know and can find on the internet......I can not get this thing to thicken. I have hundreds of parts to do, so I think I am just not getting it. We do not need much detail, I am fine deleting surfaces, radiuses, small geometry etc... as long as the overall size and shape is maintained, thats all I need. I know that the surface has open edges (indicated by the blue lines). however I do not know how to quickly clean them up so that it will thicken into a solid. I dont even care how thick, 2mm or .002mm........just need a solid. Anyone have any pointers? What am I missing, this cant be that difficult is it?
