Autodesk Inventor Rim Tutorial

In this tutorial you will learn the basics of Autodesk Inventor through making a full car wheel. The tutorial

will be broken down into 3 parts, these parts being Car Rim Car Tire and lastly the assembly, where

both parts will be attached to display a full 3D model of the car rim.

1. To start off you are going to open up Autodesk Inventor, then create a new part file. To

create a new part file you are going to click the top left button, from there you are going

to click New then click on the Metric tab. From the Metric tab you are going to scroll

until you find the file type called Standard (mm).ipt. After you have selected the

correct file

type, click the

OK button and

you will be

brought to the

main screen.

2. When brought to the main screen for inventor it will look like a blank grid, this is your

design area. Before you begin, you should start by right clicking on the grid and making

sure that Snap to Grid has a checkmark next to it, once this is done continue. Along

the top bar you will find various tools such as Line, Circle, Arc, Rectangle, Spline and

more categorized under Draw. For this particular tutorial we are going to be making a

Car Rim, to start you are going

to click the Circle button, then

click on the center point on the

grid and extend the Circle

outwards. Once you have created your circle you are going to click the Dimension

button, and then click on your circle you just created. After clicking the circle a box

should open up with a measurement inside of it, this number does not matter, and for

the sake of this tutorial you are going to change it to say 300 mm, you can then right

click anywhere on the grid and click Done. If you ever need to edit this measurement,

you can right click on the existing dimension and change it from there. After changing

the size, you will most likely have to zoom out, as the size of your circle has now been

changed, to do this you can use the scroll wheel on your computer mouse to zoom out

to a better viewing angle.


3. For the next part you are going to use the Modify category on the top bar. From here

you are going to click on Offset. What the Offset

feature does is makes a copy of the drawing you have

and will make it either smaller or larger while keeping

the same center point. You are now going to click on

the circle you just dimensioned and move your mouse

inwards, this will create a smaller circle inside of the original circle. Once again, you are

going to dimension this inner circle and this time change the size to 275 mm.

4. You will now turn this drawing into your first 3D part. In order to do this you are going

to click the Finish Sketch button. After clicking Finish Sketch you will now see your

drawing on an angled view, from here you will click on Extrude under the Create

category. A new window will open up, keep all of

the settings the same, only change under where it

says Distance and change it to 90mm then

click OK. What you have now is a 3D hollow

cylinder; this is going to be the base for your car

rim. You are able to rotate the object however you would like by using the cube in the

top right corner. On this cube, click the side labeled Front. You are now

going to make edits to your 3D model, to start, click the Create 2D

Sketch button in the top Left. Using your mouse, click on the front face of

your Rim; this will bring you back to the screen where you first started.

5. On a car rim, the top and bottom center of the rim are angled, in order to do this you

are going to use the Offset and Dimension tools again to create a circle that is

315mm. Click Finish Sketch and then click on Extrude, you are now going to click

inside the new ring you just created. You may want to change the viewing angle at this

point so you can see what is being extruded. You are now going to change the direction

that the extrusion is moving. You are now going to

change the number to 8mm and click on the arrow

pointing right. After clicking the right arrow, inventor

tends to highlight the wrong button along the left side, if

it does, just click the top one again. Once all of the

settings look like they should, click OK. You are now

going to rotate your Rim and redo this entire step for the

other side of the Rim. After this is done, you can move onto Step 6.


6. From the side, your model should look identical to this. To make this look more like a car

rim you are now going to use the Chamfer tool found in the Modify category. After

clicking on Chamfer you are going to click

on adjust the setting to match the ones

in the following picture. Before it will

allow you to click OK you will have to

select a Face. This means that you

need to select a flat surface on your model that will be adjusted. The faces that you are

going to use are the 2 bigger rings that you created. The face is the part that is

highlighted in blue in the picture to the

right. After clicking that face, Inventor will

now want you to select an Edge this is

the part that will actually be angled. To

find the Edge, just use the White line in

the picture as a reference. You are going

to have to repeat this step for the other

side of the Rim as well.

7. You are now going to use the Fillet tool which is found under the Modify category,

after clicking the Fillet button a new window will appear, under where it says Radius,

change whatever number is there

to 2 mm. You are now going to

click on the 2 edges on the inside

of each outer ring. This step must

be copied to the other half of the

rim as well. After you have done

this to both sides of the rim you

are going to apply a second Fillet

to the inside cylinder, start again by clicking the Fillet tool and set the Radius to 10

mm, click the inner ring on both the top and bottom then click

OK.


8. Rotate your rim back to the Front angle using the cube from earlier, you are now going

to click on Create 2D Sketch again, then click on the top ring of your rim. When

brought back to the Sketch view, you are going to create an Offset off of either of the

highlighted circles. Using the Dimension feature, change the dimension to 40 mm.

Now return back to 3D view by clicking Finish Sketch. Click

on the Extrude button and Extrude the new Circle inwards

20mm using the button with the right facing arrow. You are

going to have to cut about 10 mm off of the top of the center

piece. Start off by clicking Create 2D Sketch again and click

on the new center cylinder you just made. You are now going

to continue to use the Extrude feature, however instead of

creating a new solid, the Extrude feature is going to be used

to cut away existing solids. Right after you are brought back to the Sketch page with the

grid on it, there should be a highlighted ring around the center cylinder on your rim. If

this has been completed click

Finish Sketch, then click on

Extrude. Set the settings to

match the picture to the right.

The button that is boxed off is

known as the Cut tool, it will

delete anything within its

path.

9. You are now going to begin the design of the inside of your rim. This will require using

different drawing tools of your choice. For the purpose of this tutorial we are only going

to make a simple design, if you feel comfortable enough to create your own design then

feel free. You are going to start off by clicking on the Create 2D Sketch button again

and then click on the top face of your rim. To start, draw 2 lines, the first one starting at

the center point and going straight up, and the second one also starting at the center

point but going to the right. You can now click the Dimension tool and Dimension both

of these lines to be 148 mm. What you have now created is your workspace, we are

only going to design our rim in that corner, the reason for this is because of the Circular

Pattern tool which we will use later on. You are now going to click on the Offset button

and click on the lines you just created, then drag your mouse inwards to create a smaller

offset. This next part gets complicated, you are going to have to use the line tool to


connect the top of original 148mm line and the offset

line, however the line will be invisible same with the top

part of both lines, if you look at the picture you can see

where exactly you are connecting these lines, you are

going to do the same for the other 2 points as well.

When that is completed you can click on the Finish

Sketch button, then click on Extrude and then on the

arrow facing right button, if the cut button was

automatically selected when clicking the Extrude right

button, just go ahead and click the button directly above it, the top in the column.

10. If all has gone well up to this point, then what you should have now is something that

looks identical to this picture. From here you are

going to click on the Circular button under the

Pattern category and select the newest part

that you extruded, the selected area should now

turn to a different colour, you are now going to

click the red arrow button, then click on the

outside ring of your rim. The two parts selected

in the picture to the right are both the Features

and Rotation Axis. After selecting the rotation

axis you will now be able to edit the numbers inside of the Placement area, only

change the first number to a 10, and then click OK.

11. Your rim is now nearing completion, click Create 2D Sketch and click on the spokes of

your rim. Using the same center point, draw a circle and using the Dimension tool,

change the diameter to 60mm. Click Finish Sketch then click on the Extrude

button, select the circle you just created, set the arrow direction to symmetric and set

the Distance to 16mm then click OK. Now using the Fillet tool select both the top

and bottom part of the newly extruded cylinder and fillet them both using a 2mm

radius.


You have now completed your rim! To finish the entire wheel, continue on and finish tutorials 2 and 3 in

order to build the tire and assemble the wheel and tire together.
