That’s it, no extrudes or anything, just practice importing an image to onshape and tracing it.
Units : MM
Step 1) Inscribed Triangle . Dimensioned to 22. Centered at origin
Step 2) Make 1 vertex of triangle vertical with the origin. This will define the shape
Step 3) This is what your shape should now look like :
Step 4) Use the scissor tool to delete the top 3rd of the circle
Step 5) Connect the 2 points (make sure it’s defined)
Step 6) Perform 2 extrudes (25 and 35). :
Step 7) Fillet as shown:
Step 8) Add a shell:
Step 9) Final product:
To dimension and angle in onShape, you click on each side after the dimension tool
Step 1) Create a rectangle centered at the origin with a height of 20 and width of 30:
Step 2) add an arc as shown. Make sure it’s dimensioned :
Step 3) Now the bottom:
Step 4) Extrude the shape by 25MM:
Step 5) un-hide sketch 1
Step 6)
Go into sketch 1 and create 2 MM offset on the top arc and on the bottom arc, then connect their endspoints with lines :
Step 7)
Final Result
Do Your best to draw this shape. You have the whole period to work on this.
We will work on the parts studio again on Monday.
Some Examples:
Use the spline tool to draw 1 shape from here.
Extra credit if you draw 2 shapes. To get extra credit, these must be drawn well!
Use the Spline tool to make a picture of a ghost
This is worth 5 points. You can see examples of grades a
3 out of 5
4 out of 5
5 out of 5
Or you can do a comparable one
Below is what some students have already done :
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
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:
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:
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!
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:
Step 4) the outer circle and the rectangle should have a 25 MM extrude
Step 5) The connecting shape is a 10 MM extrude
Step 6) Create your own shape and do a revolve
Step 1) create a 5 sided
Step 2) Create a line for the revolve
Step 3) Make that line parallel to the line of the polygon using the parallel constraint
Step 4) Revolve the polygon over the line:
Step 5) That is a sideways look at the front. Change the 3-d angle and you can see this :
Step 5) Create a rectangle and dimension it to 20×30 and use an extrude on it.
