Autocad Inventor 2011- How to Make a Widget

Introduction: Autocad Inventor 2011- How to Make a Widget

About: I am Matthew Enderle, and my instructables are based on electrical and computer sciences.

I will attempt to teach you how to make a wheel axle in Inventor 2011 Pro. You will see my start to finish description on almost everything. I will show individual parts to assemblies.
This is meant for the people who might have not used this before and want to learn, or for experienced users who want to learn more. For beginners you can apply almost anything from this into any other projects that may present.

Get AutoCad:
You will need to go to  and register and download AutoCad Inventor 2011. You will need a ".edu" email in order to receive it for free with a three year licence. If you don't have a ".edu" Email, message me and I will work something out for you.

A little about me:
I am in my second year of high school and have been sponsored by Kondex in Wisconsin, US. I work in AutoCad and Solid works. Currently I am working with my school on a large project and I am in charge of the 3d Stress analysis in Inventor. I am using my vacation time to make this tutorial with the hopes of winning the laser so we can use it to engrave utensils and other stuff on the grill.

To see my project I'm am in go to

Let's continue on to out next step.
Please vote for me to win, I really need this.


Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1:

1. You may work better playing some of your favorite tunes or genre on your pc, ipod, or any other sound device.
2. If you don't get something reread it 2 more times. If you are still confused, then you can message or get a good rest, even a 2 hour nap works!

Step 2: Getting Ready

You will need to get to know the program. Follow the pictures bellow to see what each button does.

Step 3: Starting...

Q's and A's

Ok what is a widget?
A: There is no one thing called a widget. The term is used generically like gadget or gizmo.
It's often used in an academic context, especially in business schools or economics classes. For example, an economics professor might talk to her students about "the supply and demand for widgets," or a marketing teacher might ask his students to develop "a plan for selling widgets." By using a generic term they keep their students from being distracted by the item itself.

Q: What exactly can this do if i machined this part.
A: This part will do NOTHING as of it's current state. If you can use this to run something, great, as of this is only for a tutorial on how to accomplish this.

Go to Step 4 for a Video Method
Go to Step 5 for Dimensions

Step 4: Option 1: Video Method

You can find the video on Vimeo if this doesn't work for you.

Quick Dimensions:
All Fillets are 0.125 in
All Chamfers are 0.125 in

Step 5: Dimensions

First you will want to watch the first part of the video from Step 3 if you could so you have a much better idea on what you are making.

Otherwise the picture bellow is what you part should turn out to be.


Step 6: Layout

This is the Orthographic layout of what we will be making.

Step 7: Circle Face 1

1. Create a new Part. At the top it should say Part1.
     In the Middle it shows an orange dot. That happens to be the origin.
2. Click on the "Circle Tool" in the toolbar and click on the origin. You will need to enter the number "1" and hit Enter.
     When every you type a command NEVER type the "s.
3. Click on the "Finish" key.

Step 8: Circle Extrusion 1

The First image is what you should have currently.

1. Now that you have your circle you will want to click on the "Extrude" button in the toolbar.
If nothing changes on your part then click on the circle's face.

Step 25: Thanks!

Hello again! I would just like to say thanks again for reading or watching this tutorial. I am hoping that you can take the information from this tutorial and place it into your own parts and later assemblies. I'll post a tutorial on that later, but not now obviously.

    Great video, enjoyed it. The only thing I would comment on as a HS Cad teacher, I try to get my students to NOT delete their Dimensions before turning the sketch into a feature. The great thing about inventor is that you can go back to any step and change any one thing, if you keep the dimensions on that make changes quicker and easier and the dimensions go away anyway when you make it a feature (extrude , rotate whatever).

    I forgot to metion that you can see my latest project which is a computer that was designed entirely inside Autocad.


    Reply 8 years ago on Step 10

    Thanks! I mainly delete the dimensions myself since I manually add them later. I personally like the slate to be clean and then in the sketch I like to manually add them so that I can position them the best way so I can read them and make them.

    Nice Work Matthew. You put a great deal of time into it! Best of luck with the contest! Is it too late for others to vote yet?

    Wow... i can't wait to show off in class now! It's cool we use the same software...
    Will you do more kewl thangs?!


    Reply 9 years ago on Introduction

    You actually can get it free!
    Read the "Get AutoCad:" section on the intro!


    Reply 9 years ago on Introduction

    You can continue installing and activating the program for 3 years. Did you sign up at You then need to download Inventor. Currently it won't let you activate, I will need to help you on that. Tell me when it is installed.

    I'm so sorry. My dad says he doesn't want anything installed on my computer. It was very nice of you to do what you did though. And the email, well that I won't mess with. Thanks again.
