- [Instructor] In our previous exercise,
we added some splitting elements and then split our final
surface to get our basic form for our sheet metal parts.
Now we need to go in and add a couple
of additional features, as well as modify this split.
Now we have to be careful here.
If we're going to modify the split, last thing I want to do
is use it for a feature that comes after it
within the historical graph,
or the parent/child relationship that I've talked about.
So I don't want to use the actual split to create anything,
I'm going to come back and eventually modify it.
So I'm just going to right-mouse click on the split.
I'm going to go down to parent/children and with that
I can see that I have my main body.
This is one of the reasons why I like labeling things.
I can right mouse click Hide/Show.
And I'm going to hide the split so I don't accidentally
grab it for something.
Next thing I'm going to do is I'm going to go
to Offset 1 and I'm going to double-click on it.
I know that made that inside split here,
and what I want to do is I want to use the
initial element from this slab.
I'm going to right mouse click Hide/Show, select OK.
Now with that, I'm going to go in and do another offset.
This offset, Reverse.
This is going to be that 85
from the initial distance divided by two,
because I want to create a couple of holes at each end
that are basically in the center of the part.
Now you'll notice that I created this surface
and it placed it into the split geometrical set.
I don't want it in the geometrical set,
what I want is this in the Operations geometrical set.
So I'm just going to right mouse click on it,
change geometrical set, place it where I want, select OK.
Now I'm going to right mouse click on Operations,
and I'm going to say Define in Work Object.
That way, everything I do goes into Operations.
Now that I have that in there, I'm going to go in
and do an intersect.
Intersect from this main body to this offset, select OK.
And now I can hide that offset.
What this does is it creates a curve for me.
That curve sits right in the center
of that flange and that cutout.
And I'm going to reference this curve to create
a couple of points, so I can create a couple of
cylinders to make my holes.
Now the first thing I'm going to do is I'm
going to make a point.
It's going to go on this curve.
And I want it measuring from this back-end.
So I'm just going to reverse the direction.
You'll notice that now I'm measuring from this area.
And I'm just going to shoot in 30mm.
There's my first point.
Now the next point I need to create a reference
out here somewhere.
Remember with the splitting elements,
I'm going to Hide/Show this plane,
I eventually came back and split this surface
at this location.
If I look at the split, you can see there's my split edge.
So I need to measure from that point.
It's not right at the very end point,
so I need to create that reference.
Let me go ahead and hide that split so I don't, again,
accidentally do something I don't want to do.
For that reference I'm going to do an intersect,
and intersect this center curve with that splitting element.
And again, it creates a point.
I'm going to use that point as my reference.
So I'll create my third point.
Default Extremity is this point here.
Let me zoom up to make sure I get it.
And for that, it's 30mm.
Now that I have those two points placed correctly,
I'm going to make a couple of additional splitting elements.
So I'm going to go into splitting element.
I'm going to right mouse click, Define in Work Object.
Under the extrude function, all the way to the very end,
we have cylinder, so I'm going to double-click on that.
I want a cylinder that goes from this point.
For my direction, I'm just going to specify my XY plane.
Limit 1, Limit 2, drag it out, make sure it's big,
or you can just simply hit Mirrored Extent.
As far as my radius, I'm going to go in and say
I want an 8mm radius and hit enter.
And I'm going to do the same thing with this point.
XY Plane, turn on my mirrored extent, 8mm radius,
select OK and Cancel.
Now that I have all of these elements in place,
I have my cylinders inside of my splitting elements,
I'm going to go ahead and hide everything
that I no longer need, so I'll just take my slab,
main body, my intersects and points, hide that.
I'm going to go back up to my split number one,
I'm going to Hide/Show.
I missed one, let me get that.
At this point, I want to modify that split,
and this entire time I added these modifications,
I never once used that split as a reference
to create something else.
Again, if I go right mouse click, and go to Parent/Children
I can verify that, because it has no children.
These are the things that made my split.
You'll see these are the four elements,
the Main Body, the Parallel, the Plane and the Offset.
So for this, I'm just going to simply double-click
on the split, and I'm going to add in that cylinder
and the same here, I'm going to add in that cylinder.
Doesn't look like anything happened,
but you can see the cylinders are in there.
I'm going to select OK.
Now when I hide these, you can see I have the
appropriate holes in the right location.
Now that I have my final surface, with my holes,
everything is done, I'm going to switch over to Part Design,
we're going to go into Start, Part Design.
And I'm going to go to the part body,
right mouse click, Define in Work Object,
and I'm going to generate a thick surface.
Pick my surface, reverse my direction,
and we'll go up 3mm for my final solid.
Now, as you can see, I have my solid.
I can go ahead and finish this off.
I can add some edge filets here, here, and here
to break those corners, just good practice.
If I make a modification to one of my elements,
for example, I can quickly and easily
make changes to this.
If I go to my initial inputs, for example,
and let's say double-click on this sketch,
I can take the sketch, move it up, go up to 30mm,
I'm going to exit out and it updates incredibly fast.
You'll see everything updated, moved, shifted,
just the way we wanted.
Be sure to save your part.
