Hi,
There are two ways you can get the Check-plate finish you are asking for. It will depend
on what you want to do with it as to how you create it.
Appearance method.
Select your component you want to put the pattern onto. Right click and bring up the menu
and select Appearance.

In the Appearance Library under the Metal and Steel sub-menus you will find
Steel Diamond Plate and several options. You may have to download the Appearance
from the Fusion Library.

Simply download and then drag the appearance onto the Component as you would
with any other Appearance or Physical material.

I personally prefer the 3-tread style.

You have suggested that you may wish to actually Fabricate the Check plate pattern.
While making it LOOK like check plate is easy, if you want to MAKE it check plate then
you will have to model it. This should be fairly straight forward as check plate is just
a repeating pattern so all you need to do is model the pattern and then set up a
Rectangular Pattern.

It really comes down to what you need it for. If you just want to see what it
will look like then put the appearance on it. Realistically I cannot think of a
reason you would want to actually Model it unless you actually planned to
manufacture it. If I had an application where I needed a plate, knowing that
I would simply order check plate then I would just model the plate. It is a lot
of work for little benefit.
Cheers
