Using the Extrude tool

Making 3D models is not easy, actually it's very hard. One thing you need to get used to is the Extrude tool. It took me hours to try to get it to do one thing. I couldn't get it until I saw my professor do it in less than ten seconds.

What I was trying to do was to make the extrude tool grab one face of a box and extrude it inward.

1) So I started with a simple box. 

(Those who don't know how to make one, choose the polygons tab and choose the box. It's the second icon)

2) Next right-click and and drag your mouse over Face and let go. This way you won't choose the whole object and you'll just select one face of the cube.

3) After that click on the top face, then click the extrude tool (it's the 16th tool from the left in the polygons tab) once you click on the extrude tool then click on the expansion tool on the left-side tool bar. Once you do that use the red and yellow handles to extrude the top face in.

4) Then click on the center top face and click extrude once more. Do not click on the expansion tool this time.

5) Finally, in the picture above you can see a blue handle. Click and drag that downward. This will make the box extrude down, making a hollow center.

6) Then your done and you just created your own hollowed out 3D box.
