Concept; A Face of a shape can be its own new plane for sketches

The Assignment. Part 1

Step 1) Create 3 circles whose radii are 10,20 and 25 MM . Make sure it’s fully defined (no blue) .

Step 2) Extrude the outer rim :

Step 3) Create a new sketch on the face of the outer rim. Call this sketch “sketch on face”:

Step 4) Create an extrude on this plane. You can do whatever you like, below is one example of it could look like:

Step 1) On the front plane, create these 2 circles dimensioned.

Step 2) Add an Extrude

Step 3) Now make a sketch on the TOP plane and use the Use project tool to create a line with the inner circle. Click the image below to expand the image.

Step 4) The top plane now looks like this. The line highlighted in yellow is what we created in the prior step with the Use command:

Step 5) Create a trapezoid with that line as a base. Something like this :

Step 6) Take a screenshot of this and put it into a google doc. I need to see the above marks (showing that you used the “use” command)

Step 7) Make a second picture. I want a 5 sided shape and for you to revolve that around a line. Submit that as the second screenshot.

On the Top plane, make this shape. Ensure the corner is centetered at the orign. Use Corner rectangle:

Step 2) add teh arc:

Step 3) Lines and make 1 tangent:

Step 4) Turn on “show constraints” and take a screenshot. Make sure that you have the same constraints that mine does

Below is the a screenshot of what your constraints should be :

Step 1) Crate a 2.5 by 2 rectangle and use Corner, centered at origin

Step 2) Add 2 points and make them midpoints:

Step 3) Add a construction line between the midpoints (link)

Step 4) offset the perimiter by 0.25

Step 3) Extrude the outside only:

Step 4) Add a 0.1 Chamfer to one side:

Step 5) On the other side, add a small filet.

Step 6) Play with the chamfer and fillet(increase sizes) until you understand the difference. In your google doc paste a screenshot of the 3 shape so I can see the filet and the chamfer . And explain the difference, physically, between the 2

Step 1) Make a corner rectangle that is 2.5×2 , centered at the origin (all black lines 🙂

Step 2) add 2 points to top and bottom and make them “midpoints”

Step 1) Create a new empty sketch and draw 2 lines that meet. The lines should be 3 and 4 in length and should connect at one point. They should be dimensioend to be 3 and 5 but they will be blue and that is ok

Step 3) Dimension the angle to 45 degrees. Link . You shoul dhave something liek this (your orientation/angle might be different)

Step 4) connect the vertices to make a triangle. Picture:

Step 5)

Step 6) Add a chamfer. Take a screenshot and submit on classrom
