1.

From Create, Geometry create a Cylinder with the Height of 14cm and the Radius of 3cm. Right

click on the Cylinder and select Convert to>Convert to Editable Poly.

2.

From the Modify tab click on Polygon icon in Selection rollout menu and select the bottom

polygon. Click the little box next to Bevel, change the Height amount to 0.2cm and the Outline

to -0.2cm. Click the check mark for OK.


3/38

3.

Extrude the same polygon with an amount of 0.2cm.

4.

Inset that polygon with an amount of 0.1cm.


4/38

5.

Again, extrude the polygon only this time change the amount to -0.2cm.

6.

Bevel the selection with a Height of -0.2cm and an Outline of -0.5cm.


5/38

7.

Bevel again, only this time change the Height to -0.1cm. Leave the Outline to -0.5cm.

8.

With the same polygon selected, click the Inset button, change the inset amount to 0.5cm, click

2 times on the plus sign to apply the inset two times, after that click on the check mark for OK

and a third inset.


6/38

9.

To convert the selection to Vertex hold down CTRL and click on the Vertex icon.


7/38

10.

With the vertices resulted from the conversion selected click on the Weld button and change

the amount to 0.25cm. You will now see all the vertices snap together as one.

11.

Change the selection mode to Edge, select every other edge and click on Remove.


8/38


9/38

12.

Select the highlighted two edges an click on Loop to make a loop selection.


10/38

13.

Chamfer the selected edges with an amount of 0.025cm.

14.

Make a Loop selection like we did in step 12 and chamfer the edges with an amount of 0.1cm.


11/38

15.

To continue this 3d modeling lesson select the top polygon and Bevel it, change the Height to

0.2cm and the Outline to -0.2cm.

16.

Extrude the same polygon 2 times with an amount of 0.2cm.


12/38

17.

Inset the selection with an amount of 0.1cm.

18.

Extrude the selection with an amount of -0.3cm


13/38

19.

Inset with an amount of 0.15cm.

20.

Bevel the selection with a Height of 0.15cm and an Outline of -0.05cm.


14/38

21.

Inset the polygon 2 times, first with an amount of 0.1cm and second with an amount of 1cm.


15/38

22.

To be more accurate with the 3d modeling example we need to make the can "lip" a little bit

thinner. So select the polygons you see selected below, Use Selection Center, right click on the

Select and Scale tool, change the Offset:World to 103 and press Enter.


16/38

23.

Now select the outer polygons and click on Extrude button. Change the extrusion type to Local

Normals and the amount to 0.02cm.


17/38

24.

Make a Loop selection of the following edges and Extrude them with a Height of -0.02cm and

the Width 0cm.


18/38

25.

Make another edge loop selection and chamfer them with an amount of 0.1cm.

26.

In this 3d modeling step we will fix the Can some more, select the top middle polygon and press

Grow the selection 3 times. Scale the selected polygons using the Select and Scale tool to 105 in

the X and Y axis direction.


19/38

27.

In Vertex selection mode, using the Select and Move tool arrange the vertices like I've did:

28.

Now select the polygon and move it down using the Select and Move tool, after that delete it.


20/38

29.

In Edge selection mode select the edge you see selected below, first click on Ring to make a ring

selection and after that click on Connect to connect the edges together.


21/38

30.

Using the Select and Move tool move the vertices until you have something like below. Enable

Edge in Constraints. With this option enabled you can only move the vertices along the edges.

31.

Change the Constraints to None. Select the following edges and Extrude them with a Height of

0.075cm and a Width of 0.125cm.


22/38

32.

Now select these two edges and Remove them.


23/38

33.

To finish the 3d modeling of the can from the Modifier List add a Turbosmooth modifier and

change the Iteration to 2. Check the box for Isoline Display. We are done with the 3d modeling

part of the can. In the next 3d modeling steps of this tutorial we will create the opener.


24/38

34.

In this part of this 3d modeling tutorial we will create the can opener. From Create, Geometry

create a Plane with the Length of 2.5cm and the Width of 1.5cm. Change the Length segments

to 4 and the Width segments to 2. Using the Select and Move tool position the plane right on

top of the can.

35.

Convert the Plane to Editable Poly, go in Edge selection mode and using the Cut tool make the

cuts you see below.


25/38


26/38

36.

In Vertex selection move select the two vertices I've selected and Chamfer them with an amount

37.

Delete the polygons resulted from the chamfer of the vertices.


27/38

38.

Arrange the vertices using the Select and Move/Select and Scale tool like you see below.


28/38

39.

In Edge selection mode make 4 new Cuts.

40.

Now add Shell modifier for the Modifier List, change the Inner amount to 0.05cm and the

number of Segments to 2.


29/38

41.

Convert the object to Editable Poly once again to collapse the modifier, in Edge selection mode

make a Ring selection of the following edges and click Connect.


30/38

42.

Select these 4 polygons and Extrude them with an amount of 1cm.


31/38

43.

Make a Ring selection for the edges resulted from the extrusion of the polygons made in

previous step. Connect the with 1 segments and a Slide of 50.


32/38

44.

Add a Turbosmooth modifier from the Modifier list and change the Iterations to 2. Check the

box for Isoline Display.

45.

For the final set of this 3d modeling tutorial create another cylinder and using the Select and

Move tool position it like you see below. Change the Radius to 0.2cm, the Height to 0.05cm and

the Sides to 48.

Done!
