In this lesson you’ll learn more about using the browser, how to use the Extrude command to extrude a profile, how to set the view to the Home View, how to pan, and how to use the Look At command.

First let’s take a look at the browser. Since we haven’t named the part, Inventor gave it the name part 1. You can see this name in the top of the browser, and in the title bar. Below the name is the Master View Representation, which we’ll talk about later, and below that is the origin of the part. If you click the plus sign, the origin expands to show all three coordinate planes, the coordinate axes, and the center point. Below that you can see the sketch, and the end of the list. When you add features to the part, the list in the browser will grow. So, try to be aware of how the list changes.

We’re in the sketch environment, and in order to extrude the circle we need to be in the Part Modeling environment, so click the Finish Sketch command. Now that we’re in the Part Modeling environment we can extrude the circle.

Click the Extrude command. This opens the Extrude dialog box and the Mini-toolbar. Expand the dialog box, and then move it to the upper left corner of the Inventor window. You’ll learn about the Mini-Toolbar in the next lesson, so for now I want to focus your attention on the Extrude dialog box. At the top of the shape section is the Profile Selection button, and since you only have one profile, it’s already been selected for you. If you had multiple profiles you would click this button to select the profile. The Output section is used to set the result of the extrusion operation to a solid or a surface. Leave this setting set to the solid option.

The next section is the options section. Here you can set the extrusion to join, cut, intersect, or create a new solid. Since there is no other solid to cut or intersect, the top three options are grayed out. Leave the New Solid option selected. Just to the right of the options section is the Extents section. Here you can set the profile to extend a specific distance, from its current location to another plane or face, or from one face or plane to another. Since there are no other faces or planes on this part yet, the only logical choice at this time is distance.

You’re going to extrude the circle 1 inch. To change the value all you need to do is enter the value in the window. Leave the length of the extrusion set to 1 inch.

Below the distance window are the directional icons. These icons allow you to choose from extruding in the positive z direction, in the negative z direction, symmetrically, or asymmetrically. If you choose Symmetric it will extrude ½ an inch in both directions giving you a net length of 1-inch. If you choose Asymmetric you can use different lengths for Direction-1 and Direction-2. Direction-1 is in the positive Z direction, and Direction-2 is in the negative Z direction. We’re going to extrude the profile 1-inch in the positive Z direction, so select this option, and then click OK.

If you have a 3-button mouse, hold the middle button down to move the cylinder to any location on the screen. If you don’t have a middle button, click the Pan icon on the Navigation Bar and then use your left mouse button to drag the cylinder to its new location. Once the cylinder is where you want it, type the escape key to exit the mode.

Now let’s look at the browser. Extrusion 1 has replaced Sketch 1. If you expand Extrusion 1 you’ll see that Sketch 1 didn’t actually disappear, it’s now a subset of Extrusion 1. In other words, Sketch-1 was consumed by Extrusion 1.

One last thing before we end this lesson. To change the view back to the normal view, click the Look At command located on the Navigation Bar, and then select the face on the cylinder.
