3D Tutorial: Draw a glass

This tutorial will create a drinking glass. I used the measurements of one that I had in my kitchen.

1. Draw a circle with a radius of 1.25.
2. Start the EXTRUDE command. Select the circle and end selection.
3. Enter 5.5 for the height of the extrusion
4. Enter -5 for the taper angle. You use a negative number to taper outward.
5. Use the 3DORBIT command to change the view as shown below.

The results looks like a glass, as you see on the left. (I've changed the ISOLINES system variable to 8 to give it a nicer look.) But when you use the HIDE command on it, as you see on the right, you see that it's a solid.

To create a glass, you use the Shell feature, which is part of the SOLIDEDIT command.

1. Display the Solids Editing toolbar. (Right-click any toolbar and choose Solids Editing.)
2. Click the Shell button.
3. Select your solid.
4. At the Remove faces or [Undo/Add/ALL]: prompt, you need to remove the face that you don't want to shell. For a glass, it's the top face, because you want that face to remain open. In a view like the one above, you just click inside the top face of the solid.
5. The prompt repeats; just press Enter.
6. Enter 3/32 for the shell offset distance.
7. Press Enter twice to exit the command.

Here's the result, with some shading.

Now, all you need is some water!
