The objective of this tutorial is to build on the skills learned in the Chapter 41 RC tutorial and introduce new steps, such as using a CAD drawing and post-tensioning.

Some tools and methods described in the RC tutorial are not used here. As such, it is highly recommended that you first do the RC tutorial.

This is not a particularly "aggressive" design. After you have completed the tutorial, you may wish to make the slab thinner to investigate the ramifications.

You could also use this as a reinforced concrete tutorial by making a few adjustments (for example, a thicker slab).
