I am looking for a book that teaches drafting for home study / self learning.
I have now bought my 2nd book from Amazon.com, and it isn't what I am looking for. One book was a high school level text book, and most of it is just complete the missing lines type of homework exercises, which I don't find challenging (three chapters on drawing squares, rectangles, triangles, and circles.) The other book spends (my estimate) 70% teaching CAD commands and computer techniques. I don't want instructions on how to use AutoCAD, Sketchup, TurboCAD, etc, as that will come later.
I want to develop the skills to sketch a woodworking project. I am thinking there must be somewhere a trade (or college) level text book on drafting that assumes I know how to draw a 90, 45, 60 degree angles, and I know the difference between a circle and a triangle. But will teach me to sketch in 3-D, so all the parts can be assembled on paper before I start to cut wood.
I know how to read a 'blueprint' and know how to take measurements from a drawing. What I have difficulty doing is converting my rough notes into a drawing that someone else can use.
Last time I took a drafting class was over 40 years ago for one year in as a junior in high school. Forgot a lot over the years.
TIA, Phil
