CREATING THE LEVER CRANK CAST IRON

1. Go to Insert, Drawing, select New View. Click anywhere to create a new view.2. Right click on the Sheet.1 in the specifications tree, select Properties. Change the drawing scale

to 1:10. OK.3. Go to Insert, Geometry Creation, Circles and Ellipse, select Arc.4. Set the radius of the arc to 20. Position the center of the arc at H=20, V=20. Set the starting

angle, A to 90 and drag the mouse to get the angle displacement, S to 180.5. Go to Insert, Geometry Creation, Circles and Ellipse, select Arc.6. Set the radius of the arc to 32. Position the center of the arc at H=96, V=32. Set the starting

angle, A to 270 and drag the mouse to get the angle displacement, S to 90.7. Go to Insert, Geometry Creation, Lines, and select Line.8. Create a horizontal line connecting the two points of the 1st arc and the 2nd arc.9. Go to Insert, Geometry Creation, Lines, and select Line.10. Create a vertical line upwards from free point of the right arc. Set the length to 60. Double-click

the line and click on the Construction Element checkbox.11. Go to Insert, Geometry Creation, Circles and Ellipse, select Arc.12. Set the radius of the arc to 20. Position the center of the arc at H=108, V=84. Set the starting

angle, A to 0 and drag the mouse to get the angle displacement, S to 180.13. Go to Insert, Geometry Creation, Lines, and select Line.14. Create a vertical line connecting the two points of the 2nd arc and the 3rd arc.15. Go to Insert, Geometry Creation, Circles and Ellipse, select Arc.16. Set the radius of the arc to 70. Position the arc to make sure that it is tangent with the two 20

radius arcs. Click your mouse once you have this 2 tangents located. Then, starting from the lower tangent, drag your mouse to the upper tangent. Zoom in and delete the excess line.

17. Create two 16 diameter circles located at the center point of the two 20 radius arcs created earlier.

18. Create a 32 diameter circle located at the center point of the 32 radius arc created earlier.19. Go to Insert, Dress-up, Axis and Threads, select Center line. Click on the lower 20 radius arc.

Repeat this for the upper 20 radius arc and the 32 radius arc.20. Create dimensions according to the lab manual.

CREATING THE THREE-LOBE KNOB POLYAMID PLASTIC

1. Go to Insert, Drawing, Sheets, select New Sheet.2. Go to Insert, Drawing, select New View. Click anywhere to create a new view.3. Go to Insert, Geometry Creation, Circles and Ellipse, select Circle.4. Set the radius to 11 and click on the origin. Repeat this for the 17 radius, 21 radius, and 50

radius circles.5. Right click on the 50 radius circle and select Properties. Set the linetype to 4 and the thickness to

1. OK. Repeat this for the 21 radius circle.6. Go to Insert, Geometry Creation, Lines, and select Line.7. Create a vertical line upwards from the origin until the 50 radius circle. Double click the line and

click the Construction element checkbox. OK.8. Go to Insert, Geometry Modification, Transformations, and select Rotate.9. Click on the line for the geometry to be selected, and then click on the origin for the center of

rotation, then click on the end point of the line to define a reference line for angle, set the instance value to 5 and the angle value to 60. OK.

10. Create 3, 20 diameter circles, tangent to the 50 radius circle, on the 60 degree, 180 degree and 300 degree lines measured clockwise from the first vertical line created. Double click on the 3 circles and change them to construction elements.

11. Create 3, 14 radius circles, tangent to the 21 radius circle, on the 0 degree, 120 degree and 240 degree lines measured clockwise from the first vertical line created. Double click on the 3 circles and change them to construction elements.

12. Go to Insert, Geometry Creation, Lines, and select Bi-Tangent Line.13. Click on a 10 radius circle and a 14 radius circle next to it. Repeat this and create another 5 bi-

tangent lines connecting all 10 radius and 14 radius circles.14. Create 3, 14 radius arcs to connect the 3 gaps between the bi-tangent lines.15. Create 3, 10 radius arcs to close the profile.16. Go to Insert, Dress-up, Axis and Threads, and select Axis line and Center line.17. Click on a 10 radius arc and the 11 radius circle at the center. Delete the 11 radius circle axis line

and center line. Repeat this for the remaining two 10 radius arcs.18. Go to Insert, Dress-up, Axis and Threads, and select Center line.19. Click on the 17 radius circle.20. Create dimensions according to the lab manual.
