Step 1) Use the Spline tool to create a bat shape. The more complex the shape, the more the points.

How to Dimension over a Construction (mirror line)
\
After offset, make sure you’re points are coincident– Watch the end carefully!
Curve Point option of plane
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
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!
Revolves and Shapes with Symmetry
Do now
Step 1) Clear out an old do now. Create a center point circle with a radius of 20:
Step 2) Make a diameter
Step 3) Use the scissor tool to cut the bottom half of the circle off
Step 4) Make a vertical construction line right up the middle of the circle
step 5) Add 2 lines symmetric about the construction line
Step 6) the angle should be 40 . How to dimension an angle
result :
step 7) Use the scissors tool to cut out the center arc.
step 8) MIrror the shape over teh diameter:
Step 9) Extrude 1 half of shape by 45 MM
Step 10) Extrude the other half by 27 MM
Part II . Your own shape
After you take a screenshot of the above shape, do a different type of 3-d model. You can use anything else whether its a revolve, a sweep or a loft
To get full credit on this you must use either a sweep or a loft as your 2nd 3-d shape.
2 Revolves and add a plane
We are going to make 2 revolves
Step 1) create a 20×30 rectangle with centered at the origin. “Center point
Step 2) Add a 3 point arc using tangent
Step 3) Create a fillet with a radius of 7
Step 4) Add a construction line , dimension it to 28 MM away from origin
Step 5) Revolve the shape around the construction line to produce:
Step 6) Create a reference plane. Make sure you connect it to the top plane :
Step 7) Take a screenshot of the above shape and paste it in google doc
Step 8) Create an extrude of a complex shape. Your “complex shape” should be at least 3 parts (like a circle a rectangle and something else). Your extrude should go to 2 different heights
Take a final screenshot into the google doc
Rectangle Center with Extrude
Step 1) open any prior do now and delete the sketch and restart
Step 2) make sure that the workspace units are MM
Step 3) create a rectangle with its center point as the midpoint on the origin. The rectangle should be 30 by 20. See video below
Step 4) Create a semicircle with a radius of 15 (use or or make a circle and cut half off with the scisoors tool
Step 5) Create an isosceles triangle like this (Dimensions do not have to be exactly like mine)
The remaining steps are up to your discretion
Part I . REVOLVE
Step 6) Create a line somewhere and revolve the shape around it
Part II) 2 Extrudes with your own shapews
Create a shape with multiple elements (maybe a circle and a rectangle) Create 2 extrudes with different heights like we did before
Screenshot and put in google classroom.
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:
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
3d Day 2
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.
Screenshot and submit to google
Onshape Do Now Partial Circle
Step 1) Create a 30 mm horizontal line with its right endpoint on the origin.
Step 2) Add a point to the line, then use then use the midpoint constraint so that it is a midpoint.
Step 3) Make a 3 point arc starting at the midpoint and centered on the left end of the line segment:
Step 4) Dimension 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.
Step 8)
When done, paste a screenshot in the google doc, then go here
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:
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:
Step 6) Select the cut tool
Step 7) remove the indicated region:
Step 8) Select the mirror icon and the mirror line indicated:
Step 9) Reflect everything!
Step 10) Use the scissor tool to delete the mirror line.
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.
