Instance parameters for variability within a type

- [Instructor] Now that we have our basic form created,…let's add one more parameter and then drop it into our space…and see how it looks.…And that's a raised portion of the countertop.…Create two new reference planes for it.…And in this case I'll decide that I want the depth,…to always be one foot.…So I click on the reference plane,…and then click on the dimension string.…

Side one foot, and then lock that dimension.…Then for the length of this raised portion,…I'm going to create a new parameter…called Raised Length,…and in this case it's going to be an Instance Parameter.…Set the default to four feet.…

But as you'll see when we go back into the project,…you'll be able to grab this and change it,…and it won't affect other instances of the same family.…Let's add our extrusion to it,…in this case, we're going to put our start point…at height.…And then let's start by making the end point…at an arbitrary point above that.…

And go ahead and lock to the reference planes…like we've done before.…Now if we look at this from the front,…
