- [Instructor] The modeling ribbon tools are a super set
of the edible poly tools available from the modify panel,
meaning that there are tools on the ribbon
that are not available from the modify panel.
And one of the most valuable is called swift loop.
Previously in the course we've seen
how to insert edge loops, either by using
the quick slice or the cut tool, but in this case
neither one of those tools would be helpful to me.
I want to add an edge loop here at the bottom
of my seat cushion in order to resolve some more detail.
So let's select that object
and we can isolate it, just hide everything else.
The keyboard shortcut is control alt Q.
Orbit around with alt and middle mouse.
So here's the issue.
I want to add an edge loop here in this curved area.
I would not be able to do that using quick slice
because it's a plainer shape
and it would just chop through in a flat zone here
and it would cut through some stuff
I don't want to cut through.
And if I use the cut tool,
I'd need to micromanage that process
and cut through each polygon individually,
again because this area has some complex curvature,
but the swift loop tool will be able
to insert a new edge loop based upon
an existing polygon loop,
regardless of the shape of that polygon loop.
So basically we can chop through
all of these polygons proportionally.
So with our object selected,
we'll go up to the modeling ribbon.
Make sure we're in modify mode.
Go down to the bottom of the stack by clicking
previous modifier a couple of times
until we see editable poly displayed
and we have all of our tools available.
And we can do this with show end result turned on or off.
Let's turn it on so we can get a better sense
of where our new iso lines are going to be created.
Swift loop can be executed
from within sub-object or object mode.
We don't need to be in a sub-object mode.
Swift loop is found on the edit panel.
Just click on the swift loop button
and then hover your mouse on the model
and you'll see a preview of the new edge loop
you're going to create.
And I want to create one down here near the bottom.
So I'll just hover my mouse over one of these edges
and click to create that new edge loop.
And there it is.
I can exit out of swift loop
and if we want, we can see this without show end results.
We can turn that off just to see.
Here's the raw polygon structure.
And we've chopped through
all of these polygons proportionally.
In other words, the same proportional distance
along the original crossing edges.
So for example, if we wanted to cut at around 10%
from each one of these edges, then we could do that.
Here I've got it about 50%.
Okay, so that is how to use swift loop.
We can exit out of isolation, once again,
with control alt and Q.
