- In the previous movie,
we saw how to create a primitive using Keyboard Entry.
Now we'll use the interactive method.
Which is clicking and dragging the mouse
in order to set the various parameters for a primitive.
And because the primitives all have different parameters
the method that you need to follow for clicking
and dragging is going to vary for each primitive.
So you may need to click and drag
in a different pattern to create a sphere
versus a box versus a cylinder.
Let's start with a sphere because that's the simplest.
It really just has a center and a radius
over in the Create Panel under geometry,
standard primitives, click the button labeled sphere.
And now we're in sphere creation mode.
Go over to their perspective view
and click and hold the mouse button down.
When you click, you're creating the position or the center
of the sphere, and then when you drag outward or inward
you're setting the radius
and we can see the numbers change over there
in the Create Panel.
Release the mouse
and we've created our first sphere
and it's got a random color assigned to it.
We're still in sphere creation mode.
The sphere button is still lit up.
We can click and drag to create more spheres.
And again, we'll get a random color each time.
If we're done creating spheres
we can exit out of this tool.
Exiting is not performed by clicking the button again
These buttons only turn creation mode on.
They do not turn it off.
You need to choose some other tool
in order to exit out of this creation tool.
And as we saw in the previous movie
we could just simply choose some tool such as
Select Object and that'll dump us out of creation mode
but there's actually an easier way
which is just to Right Click anywhere in the Viewport.
And that'll exit out of whatever creation mode you're in
and drop you back into whatever tool you were in before
which in this case just happens to be Select Object.
All right.
So that's how you create a sphere.
Let's create a bot box, click the Box Button.
And in the last movie
we change the creation mode over to cube.
So just make sure you're in box creation method.
And then in the perspective view, once again
click and hold the mouse button down and drag.
And as you drag, you're setting the length
and width or the footprint of that box.
And you can see again, the numbers changing
in the Create Panel,
release the mouse button
and then move the mouse without holding the button down.
And that's how you set the height.
When you have the height that you want
just click the mouse once.
And now we've just created that box.
And if we're done creating boxes again, Right Click
and we'll exit out of that creation mode,
Just as before if we want to change the parameters
we can simply select some object
and go to the Modify Panel
and we have access to those parameters.
Once again, I can click
and drag on that spinner to set the radius.
I also want to just briefly introduce you
to manipulation of objects, moving them around
on the screen and in the 3D world.
And that's accomplished from the button
on the main toolbar select and move, activate that.
And you can select some object and click
and drag on one of these arrows that are marked X, Y, and Z.
Those indicate the Cardinal Directions of 3D space.
I can click and drag to move any one of these objects
in any one of those dimensions. And of course I can do that
in the other Viewports as well.
For example, if I want, I can move these spheres
so that are all above the ground plane.
So this line here indicates the X, Y plane of the world
and that's usually the ground plane.
I can click on a sphere and move it up.
So it's sort of sitting
on the floor and it's not below the floor.
I can also click on this bracket here
and that'll allow me to move in two dimensions at once.
All right, that's the basics
of Interactive Creation and Moving Objects
in 3D using the move Gizmo or Manipulator.
