- [Narrator] Oftentimes, while trying to figure out
how we might create certain hard surface models,
we will realize that it would actually be easier
to break them down into smaller components
rather than trying to model them as a whole.
For example, in this instance, we are going to create
a screw thread for ourselves by initially creating
lots of smaller meshes that we will then combine together,
simply, because it is much easier, in my opinion,
than trying to create the screw thread
from a single piece of geometry.
The way we are going to do this is by creating
a new modeling grid that will, essentially,
allow us to create the thread at a lot smaller scale
than our current home grid settings would easily allow,
which, of course, means that we won't have to adjust
and then re-adjust all of our main grid settings.
It also means that we can instantly jump back
to working with our home grid as soon as
we are done creating the pieces that we need.
So, how do we do this?
Well, there are two ways that we could go about it.
One would be to come to the helper section
in the Create tab of the command panel
and click on the Grid option.
Another, with our cursor over a view port,
would be to simply press the X key,
start to type the word grid,
and then select the grid entry
from the top of the sorted list.
What we can do now is click and drag in the view port
to create the new grid that we want,
and then right click in order to end the creation process.
If we jump into the Modify tab now,
we can make some adjustments to the parameters here,
setting the length and width values
to 20 by 20 centimeters,
and then setting the grid spacing to one centimeter.
Now, this is still a little bit bigger than ideal,
but it will help us create our meshes much closer
to the scale that we will actually want.
And that is pretty much it for grid setup.
We can change the active color of the new grid, if we want.
We can even change the grid's orientation in the view port.
Indeed, to save ourselves having to later rotate
the geometry that we are going to be creating here,
let's actually set this to function on the zed x plane.
Now, to make this having a working grid,
with it it selected we can hit the X key,
again, with our mouse over the view port,
start to type the word activate, and then click
to select the activate grid object option when it appears.
Our original home grid should then disappear
leaving our new grid set up and ready to be used.
Coming to the front view port,
let's press Alt and W to maximize
so that we can zoom into the grid as,
in our next video, we are going to use it to create
one of the component parts of our screw or bolt thread.
