Day 3 of mechanical drawing involved learning the most common drawing tools on AutoCAD. These tools included constucting lines, locking angles, drawing circles, using the heads-up display and defining a unit. Drawing lines is pretty simple; simply click to start and click to finish. Locking angles is very useful for making exact figures. This can be done using either ortho (90 degree angles) or polar (most other measurments) mode. Drawing circles is simplest by clicking for the center of the circle and then typing the desired radius into the command line, but there are other ways of creating circles for special circumstances. The heads-up display makes for easier angle and length sizing. Units are very important for models and they can be changed by going to: application- drawing utilities- unit.
