bat shape- on shape

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

Picture 1 : 4/5

Picture 2 : 5 out o 5

You can also pick a more complicted or different picture

Do an extrude on it.

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

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
