(11/09/2017) Model 2 To begin this sketch will be in inches 1. First start by turning off auto-dimensioning, and select top view. 2. Follow up by making two concentric circles, one 7 inches and the other one 10 inches, that have the center on the axis coordinates. 3. After that, make two lines one parallel to the x-axis and one that is perpendicular to the x axis that are 7 inches long and cross the center of the circles. 4. Then add lines that are 45° to the lines you already have until you have the smaller circle divided into 8 equal pieces. You can do this a faster way using the collinear function 5. After that convert all of the lines and the smaller circle int
