Join Randi Derakhshani for an in-depth discussion in this video Creating 3D shapes from 2D shapes, part of Learning 3ds Max.
When we begin the process of modeling its common to begin with a 3D Primitive or object. In this video however we'll look at tools that allow us to create 3D objects from 2D shapes. This allows us to create simple or highly detailed models very easily. A Shape is an object made from one or more curved or straight lines. Shapes in 3d Max are non rendering 2D objects, that you typically create in an orthographic view port. Here we're going to take a look at the, shapes that we have available.
In the create panel, here on the right side of the interface, we're going to go into create, an next to the Geometry button is shapes. These are Shape Perimatives and they are very simple Circle, Rectangle, Ellipse, an Arc. And they each have their own set of parameters that can be edited to suit your needs.
I'm creating one of each of them so you can get an idea what they look like. And I'm clicking and dragging within the viewport on most of these. (audio playing) So these are some of the 2D shapes that are available. There are a few more, but these are some of the basic ones. By selecting them, and looking at their parameters in the modify panel. You'll see that they all have very specific parameters. Each of them have a Rendering Rollout, an Interpolation Rollout, and a Parameters Rollout.
Some of their Parameters are very simple like the Circle which is just Radius that I can make bigger or smaller. Or the Rectangle which has Length and Width that I can change. And also something called the Corner Radius. Which will give us rounded corners on our rectangle. This Star shape has two radiuses for the inside and the outside of the star.
How many points you want, if you want to distort, the star, or fill it, which will add a curve, to one end and, to the tip, and, this area here. Most of the parameters are pretty simple. This is what we call the Egg, it's a new edition. You've got your length and width, but you can also decide if you want to have this outline in the center. If I turn that off, it just gives me a solid I can also angle it like that if I want that smaller area to be on the top or on the bottom. There are a few shapes that I haven't discussed and we'll take a look at those now.
One of those is the Text tool. If I just click in my view port it creates a default text called MAX Text. And the parameters in the Modify panel are, I have a typing area that I can type in. I can change the size, (audio playing), change the font, (audio playing) and depending on what fonts you have set in your computer. You'll get, that list, the fonts that is by default is usually Arial font, that's the one I usually see.
We have Kerning, which changes the space in between, Letting for lines of text. Another shape that is rather interesting. Two of them, I'm going to show you in a perspective view port, cause they so have a little bit of a 3D aspect to them. Helix, s just what it says. It creates a helix.i That's the click and drag in the view port method. Usually what I do is just create the helix.
Go into the Modify panel and then change the parameters. I'm going to add a few more turns, so you can see what it looks like. If I make the Radius one, ten. And Radius two, five, it'll look like that. The Height, add more turns. Bias, just pushes it up or down, up or down. (audio playing) And the other one is called Section. This one is kind of an unusual shape. Its not very interesting looking, just looks like that. But it has a bigger purpose.
I'm going to create a 3D pyramid, just one of these teapots. And then I'm going to line up this section, so that, it's on its side here. And as I pass that section over this tea pot, you'll notice on the tea pot. Change the color of the tea pot, so that it's not yellow also, there we go.
You could see where ever I move this section shape, I get an outline of where that section is. I can actually extract that outline through this shape. Then I do that in the Modify panel, you can see here, it says create shape. Just going to call it shape and there it is, right there. It's kind of an unusual tool.
We can also take these shapes and we can turn them into edible shapes, meaning we can edit them at a basic level. Here is the circle, in the Modify panel. In the modify stack here, I'm going to right-click over it. And go down here and choose Edible Spline. This gives me a sub object access to this object, at a vertex level or vertex, which is a single point in space that I can change and move that around.
(audio playing) A segment, which is the area connecting two vertices together, and the overall spline. Those are the three component levels of a Spline. In this video, we took a look at some of the shapes and their parameters. We saw how shapes could be converted into edible spline objects and further edited to meet your modeling needs. We also looked at some of the more unusual shapes like the text shape, section shape, and the helix.
