Re: drawing circle
Well …………..The Circle method draws a variety of circular and elliptical (oval) shapes. In addition, Circle draws arcs (segments of circles) and pie-shaped wedges. You can produce many kinds of curved lines using variations of the Circle method. The radius of the circle is always specified in terms of horizontal units. If your coordinate system uses the same horizontal and vertical units (which it does by default), you can ignore this fact. However, if you use a custom scale, horizontal and vertical units may correspond to different distances. In the preceding examples, the radius is specified in horizontal units, and the actual height of the circle is guaranteed to be equal to its actual width. This article will explain how to draw an involute gear using a graphical method in your CAD program that involves very little math, and a few ways of applying it to the manufacture of gears in your workshop.
