This Instructable is designed to be a friendly project-oriented walkthrough for users new to Inventor or CAD in general.  If you want to start using Inventor like all the cool kids, but feel overwhelmed by the panoply of features, options, and tools, start here! 

We'll learn about: 
Sketches and parts
Setting the Heads-Up Display and using it to define dimensions
Drawing lines
Using the Mirror tool

Plus, you'll have a design for a pair of handy test pieces to help you figure out how to size your laser-cut boxes so they snap together just the way you want!  (To make the combs, continue through Exporting Inventor Files to CorelDraw [forthcoming], then cut them on your handy local laser.)

Step 1: Make a new part

First, fire up Autodesk Inventor and create a new standard part.  A "part" consists of one or more sketches.  These sketches define one aspect of a part, such as the shape of one face of a part or the contour of a machined edge.

Select Standard.ipt and click OK to start a new sketch.

Step 2: Check Settings

Check to see that the Heads-Up Display is on and set correctly (for the purposes of this Instructable):

1.  Click on "Options" at the bottom of the Inventor menu.

2.  Click the Sketch tab and make sure that "Enable Heads-Up Display (HUD)" is checked.

3.  Click "Settings" and set Dimension Input to Polar Coordinates.  Click OK.

4.  Remember to click "Apply" in the Application Options window, then "Close". 

There are lots of other settings in here too, as you can see.  Take a look and remember them for later when there are other things you want to change!
