- [Instructor] A cross break allows you
to stiffen a flat surface in a sheet metal part,
and it's used extensively in HVAC panels
or anytime you see a big flat surface that needs
a little stiffening you can add a cross break.
So to do that just we need to start off
with a part that has something like an edge flange
around the outside.
And this is the surface here we'd like to stiffen,
so then head over to Sheet Metal,
click on Cross-Break and then just choose that top surface.
And right away we get a visual representation
of what's gonna happen here
and you can see we've got this little arrow.
If you click on it, you can flip the direction,
but I prefer to have it out.
You can adjust this band radius here,
maybe we can make it a quarter of an inch,
as well as the angle,
and then just go ahead and click on Okay.
And now you've got a nice visual representation
of that cross break that you can put on your drawing
for the sheet metal shop to add that stiffening feature
to your sheet metal part.
The other thing you might wanna do here
is change the material.
I'm gonna go ahead and click on the Material here,
Edit the material,
and I'm gonna choose something like a galvanized steel.
So come over here to Steel
and let's see if we can find
some galvanized steel down here.
Galvanized Steel, there it is.
Apply that and Close,
and now we've got a nice visual representation
of our part with a cross break
and we've changed not only the material,
but also the look of the part to show it's galvanized steel.
