Day 4 of mechanical drawing focused on coordinates and the object snap tools. The object snap tool is probably the most useful utensil for creating exact geometry. The object snap menu can be accessed by holding shift and right-click. Then you can choose if you want objects to connect to midpoints, endpoints, tangent, perpendicular, and many other options. Automated object snap tools can be found by right clicking on the object snap icon in the toolbar. Then you can select what object snaps you want on all the time. It is not suggested that you have more than 3 object snaps on at once. The objet snaps are nice but to copy designs you may have to draw extra lines. The temporary tracking can be used to speed up the process. Enabled by typing "tk", Temporary tracking is used almost the same as drawing normal lines, but the lines are not seen.
