Some years ago here on HBA, I mentioned a little gem of a book from the past, Aircraft Lofting and Template Layout with Descriptive Geometry. Recently, I've gone back to school to work on precision machining and this old book came back to mind because of my print reading class. I'm curious, does anybody else here still use these antiquated revered methods anymore after the advent of Solidworks, etc. or is this a dead art? Here is a little exercise I worked out this evening, projecting a 1-2-3 block across various projections and back to oblique.
