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.

3-d First Forays

Step 1) Create a rectangle and dimension to 30 by 50 as shown

Step 2) Create your first extrude . Use 30 mm as shown in the video below:

Step 3) Let’s make it a shell :

Step 4) Now let’s try something different. Delete the shell and delete the extrude, then delete the sketch the start all over.

Step 5) Draw a circle and a line. Don’t worry to much about the dimensions. Just make it look close to this :

Step 6) Create a revolve using the line as the axis as shown in this video:

Step 7) Mess around with the 3-d shapes and do something else…make another revolve..or another extrude or one of the others. Submit a screenshot of this below the do now

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.

Hexagon in onshpae

Step 1) Use the polygon tool to make a pentagon (5 sides)

Step 2) Dimension the side to 25

Step 3) Add a point then use the midpoint constraint on it

Step 4) Draw a construction line to the midpoint

Step 5) Use the cut tool to remove half the polygon

Step 6) Add 2 lines

Triangle Mirrored and Inscribed

Do Now

Step 1) Create the right triangle above. The hypotenuse dimensioned to 30, the vertical altitude is a construction line and the the other leg is dimensioned to 21.

Step 2) Mirror the triangle over the construction line

Result :

Step 3) Circumscribe circle that is dimensioned to 42

Final result:

Complex Shape 1 with Arcs and Constraints

Use the front plane and the make a 3 point arc centered at the origin
Picture:
Use the dimension tool to set the radius to 20 mm :
Resulting shape :
create 2 lines that are attached to the circle and that meet at a point outside the circle. Dimensions don’t matter, yet, for these. Your document should look similar to (does not have to be exact
:
Use the Tangent tool to make both lines tangent . You must select both the circle and the line as shown below:
Create a construction line from the end points of the arc:

Create a Rectangle, as shown in the video below. Watch the end carefully for how to make the points coincident. Your interconnected shape should move as shown below:
Use the Dimension tool to make sure that the height of the rect is 65 MM :
Click to enlarge image
Add a midpoint to the bottom of the rectangle:
Make a Circle centered at that midpoint
Dimension the bottom circle so that its diameter is 35 :
As you can see only the top tangent line is blue. So that’s the last item to dimension! Dimension it to 42 :
Use the trim tool to remove the top half of the circle and its diameter line:
Now your turn. In the same document. Create a complex separate shape. This shape should include a minimum of 5 simple shapes. 1 of the shapes must be an arc or a semicircle. All of the shapes must be dimensioned.
