Multi-Extrude and Revolve

Step 1) Open up any do-now that we have already done . Delete the prior sketch

Step 2) Create a rectangle with a center on the origin and a height of 40 and width of 50

center point rect icon

Step 3) Make a circle centered at the origin. The  4 points of the rectangle should be coincident with this circle. Resulting picture:

Step 4) Use the scissors tool to create this :

Step 5)  Create a circumscribed polygon with 6 sides (hexagon). The 2 vertices should be coident with the points as shown below:

hexagon coincident

 

Step 6)  Use the scissor tool to make this :

Step 7) Extrude the middle part  by 50MM and the bottom remaining hexagonal part by 30 MM. to produce:

multi-extrude

 

Step 8)  take a screenshot and attach to google doc and then delete your work

 

Part II: Your own Revolve, Seep or Loft

Create at least 3 interconnected shapes (circle, arcs, rectangles etc..). Perform either a revolve, a loft or a sweep. I will give an extra credit point if yo udo a sweep or loft!

Do-Now Multiple Extrudes

 

Step 1) open up any of our prior documents that we are done with and delete the prior work

Step 2)  Create this sketch with these dimensions. The lines from the circle to the rectangle must be tangent to the circle.

Step 3) Extrude the smaller inside circle 50 mm:

50 MM extrude

Step 4) the outer circle and the rectangle should have a 25 MM extrude

25 MM extrude

Step 5)  The connecting shape is a 10 MM extrude

Step 6)  Create your own shape  and do a revolve

3d Day 2

Step 1) create a 5 sided

5 sided polygon

Step 2)  Create a line for the revolve

line for revolve

Step 3)   Make that line parallel to the line of the polygon  using the parallel constraint

parallel line for revolve

Step 4) Revolve the polygon over the line:

revolve 3

Step 5) That is a sideways look at the front. Change the 3-d angle and you can see this :

revolve 4

 

Step 5)  Create a rectangle and dimension it to 20×30 and use an extrude on it.

Onshape Do Now Partial Circle

Step 1) Create a 30 mm horizontal line with its right endpoint on the origin.

dimension 30 mm line from origin

Step 2)  Add a point to the line, then use then use the midpoint constraint so that it is a midpoint.

add point then use midpoint costraint

Step 3) Make a 3 point arc starting at the midpoint and centered on the left end of the line segment:

make a 3 poin tarc starting at the midpoint

Step 4) Dimension radius to 15

dimension the arcs radius to 15

Step 5)  Create an inscribed hexagon using the polygon tool

Step 6)  Remove some parts of the hexagon using the cut tool:

Step 7) Make a vertical and a horizontal lines  as shown below. Note they are dimensioned.

Onshape Practice- Disappearing Mirror Line

 

 

Step 1) Make sure you’re workspace units are millimeters

Step 2) Create a 3 point arc. Dimensioned to a radiu of 30, then add a vertical line:

3 point arc w line

 

Step 3) Dimension the vertical line:

Step 4) Use the spline tool to create this :

Step 5)  Add 2 circles and dimension both of them to 12 (smaller ) and 50 (outer) as shown below:

2 circles-dimensioned

 

Step 6) Select the cut tool

Step 9) Reflect everything!

Step 11) Add 4 shapes of your choosing (line, rectangle, circle etc). Make Sure that all of the shapes are dimensioned. Submity your screenshot in google classroom assignment.
