- So I'd like to just take a few minutes here to go a little deeper into the strategy that we're going to take to begin building our Corinthian column. I'm looking at a plate from the J.M. Mauch book and this is the entire plate of the Temple of Vesta at Tivoli. And here I'll just zoom in on the bottom portion of it. And if you look at the very bottom of the image, there is a little scale ruler there, and that's going to be important to us because all of the work that I did in Renaissance Revit, I used the base diameter of the column as my primary module.
Well sometimes you'll see that some authors will break down the base diameter further into additional parts. So that's exactly what Mauch has done is he's used the module system. The module is actually half of the base diameter, so you have your overall base diameter that breaks into two modules, and then that breaks into thirty parts. So let's make sure we're clear on all the terminology here because it's going to be used throughout all of the other objects that we build. So the base diameter is just simply the diameter as measured from the base of the column, and that's sort of the primary unit in all classical architecture.
If you imagine this illustration right here, and you measured the diameter at the base of the column, that's what we mean by the base diameter. And in all of my families, I just call that parameter base diameter. That's the name I'm using. So base diameter equals two modules. A module equals thirty parts. And a part is just the smallest division that we're going to use. So on that basis, what I've done is, in each of the families is I've defined the part and the module as well as the base diameter as parameters.
We're going to have all three of those as parameters and then, of course, I've put formulas in to make sure that their proportions relative to one another make sense. We're going to be using the parts then, to help us build all of the different measuring systems, and here's just the visual again, so you can see it on the ruler there. Now just briefly a look at the terminology of a Corinthian column. This is an example from Renaissance Revit, so it's using the more traditional Corinthian column, but you've got the abacus at the top which that sort of that top level moulding.
Right below that is the bell which is the basis of all of the leaves and everything else that wraps around it. The volutes are the scrolls at the corners, and then of course we have two rows of leaves that occur in there as well. We also have a flouret and some flowers and some other accouterments that you'll see on there. Most of these components will exist in one form or another in the Vesta version that we're building from Soane's Bank of England. Here's an illustration of the medium detail version of the Soane capital that we're going to be creating, and I've kind of just pulled it apart so you can see each of the families that we're going to have to consider.
So we're going to need two leaves that you see down there at the bottom. We're going to need two different kinds of scrolls or volutes. There will be some sort of a flouret, which is right between the two scrolls there, and then of course the flower is the big, noticeable, recognizable piece from the Temple of Vesta. We have that big sort of lotus flower that kind of blooms out, and it's much larger proportionally than the flower typically is on a Corinthian capital. So each of those is going to be a separate family that all kind of gets nested in for us to create our whole.
In the next movie we'll start with the course level of detail version.
