Now, that reminds me of engineering graphics class with a T-square and sketching those darn screws/nuts/ and threads. Ugh!
Ugh to you, cool to me. Today we have computer aided drafting and the physical drafting tools are less necessary now. But there was nothing like getting down and dirty with the T-square and triangles and pencils. Remember the tool with the perforated, rotating dial that was used to create equally spaced text guide lines. It was also wonderful for creating hatched-in areas even though the professor said no, that’s not what the tool is for. But even he couldn’t see the difference in the result and it was easier than messing with the triangle and measuring off the position of each line of the hatch.
