Roughing out the piston

- To start on the piston model, from the Chapter Two folder open the 02<u>04</u>Piston<u>Start</u>Part file. We have a simple circular extrude as our starting point. On the right plane, start a new sketch. Now go Normal To. We will cut the grooves for the piston rings. Use a center rectangle and start coincident to the left edge. Make the horizontal edge 2 millimeters long. Position the center of the rectangle 10 millimeters from the top edge of the underlying geometry. Let's make the groove width 3 millimeters. Now do a revolved cut, and using a temporary axis we'll cut a groove around the model. From the Feature tab, select the Linear Pattern command. We need three of these grooves, and instead of sketching and cutting them, and for additional flexibility, patterning is a better option. Select the Assign Temporary Axis again, and this time as our pattern direction. Reverse the direction so the direction arrow is pointing down. Set the spacing to 5 millimeters and the instances to 3.…
