- [Instructor] Now I'm going to discuss
using the profile toolbar inside the sketcher.
So here, I'm going to create another sketch,
just like my sketch icon, and again, you can select
the plane you want to sketch on out of the tree,
or in the graphics window.
Once I'm in the sketcher,
you'll notice the way the toolbars are laid out.
Here we have profile, operation,
and constraint.
Here, I'm going to be speaking about the profile toolbar.
Profile toolbar has all
of your curve creation methods available.
If I select on the profile icon,
notice first thing that the sketch tools toolbar changes.
Here, it's offering you various ways
to create your first curve.
You can either be a line of a three-point arc,
and again, the highlighted orange icon
is the one that's currently active.
By default, line is active.
And the way this profile under the profile toolbar works
is you select your first point,
and I'm not holding down mouse button one,
and I'm freely moving around my curve.
As you can see, I have the rubber band effect.
Here, I can draw my length out to where I want,
select again, and I have a connected curve.
As I go around, if I click,
now I'm holding down the mouse button.
Momentarily, I'm going to drag.
After I drag just a bit, I release the mouse button,
and what happens is the curve becomes a tangent arc.
And you'll notice once again on the sketch tools toolbar
that the tangent arc icon is now highlighted.
Once I select my endpoint for my arc,
by default, it switches back to line,
and you'll notice that,
because I have my geometric constraint turned on,
it gets applied to my curve.
So here, as I continue to draw my profile,
you'll notice I get all of these help lines.
These help lines are indicating
that you'll get additional constraints placed.
If I draw my line in here at this location,
I'll get a perpendicular constraint
to the orange highlighted line.
If I move this just slightly,
you'll notice I'll get a parallel constraint.
If again, I move this a bit more,
you'll notice I get a tangency constraint
at the endpoint of that line for the arc.
So, depending upon here you draw your line at,
you'll get certain constraints automatically.
Now, you do have to take caution when you are drawing,
because it is very easy to accidentally get a constraint
you may not want, such as if I'm drawing this line.
You'll notice I get a constraint to the endpoint up here.
that circle with a concentric circle on the inside
indicates that it's going to be coincident.
If I'm not really super careful,
you'll notice that I can accidentally get a constraint
to all sorts of elements.
There's a perpendicular and a coincident.
There's one to the origin.
Let's see, right there,
there's one to the origin with a curve as well.
So, be very cautious when you're using your profile tool
to draw out a profile.
If you want to be sure that you're not going to get
additional constraints, once again,
you can hold the Shift key down on the keyboard.
And you'll notice that wherever I move my mouse,
I will not get any of those blue help lines.
As soon as I remove my hand off of the Shift key
on the keyboard and begin to draw once again,
you'll notice those help lines come back.
To finish off the profile,
I can do one of several things.
If I come over to the endpoint of the initial curve
that I drew, you'll notice I have a circle with a dot.
That is indicating that those two endpoints
are going to be coincident.
Once I select, you'll notice the profile
automatically closes and finishes off with a tool.
I'm going to go back into the profile icon once again.
I'm going to draw another line, point to point,
come up.
Again, I'm going to click and drag to get an arc
and draw my next point in, come over to my endpoint.
Now, if I don't want to close off on this endpoint,
maybe I wanted to close off at this arc.
If I click here, it'll close off the profile.
If I do not want to click here and finish off that profile,
I can come over and just simply select the profile icon,
turn it off,
and the last completed curve is what gets created.
Once again, I'll go into profile,
and another way you can end off is by simply drawing.
Now you'll notice, once again, I'm getting all these
help lines, so I'm just going to hold the Shift key down
to make sure I don't get those constraints.
I'm going to come across, pick, and pick,
and if I want to finish off at this next point,
if I double-click, by double-clicking,
it finishes off the profile automatically.
Last thing I want to talk about with the profile icon,
once again, I'll pick it,
I'll select my first point,
select my next point,
and I come to realize, well, maybe I wanted a tangent arc.
Now, at this point, if I were to draw another line,
it would be that, a line, not an arc.
What I can do is I can come up to my sketch tools toolbar
and specify that I want a tangent arc.
By selecting tangent arc, you'll notice
that the curve automatically changes to the arc.
Select my endpoint, I'll come across.
Select my endpoint.
I can do the same thing with a three-point arc.
If I want a three-point arc, I can select three-point arc,
and you'll notice that the first point is, again,
selected from the previous point.
Select my next point,
and you'll notice that this arc is no longer tangent.
This is just a standard three-point arc,
and then pick your third point to finish off that circle.
So there are many options within the profile tool itself
for drawing open or closed profiles.
Again, if you want to finish off, you can double-click.
You can use the escape key.
You can select the profile icon, once again,
to turn off the actual profile tools.
So, for here, I'm just going to escape out.
I'm going to undo a few of these,
bring my sketch back into my view,
and talk about some of the predefined shapes.
You'll notice under the rectangle,
I have several predefined shapes,
and this is where the queue line comes very important,
very handy, until you get familiar
with what some of these tools are asking for.
A rectangle is just that.
It's a standard rectangle, two diagonal points.
You get your horizontal and verticals.
And do that.
I have as well oriented rectangle.
The first two points determine the orientation
and the width, and then the third point
determines the length of the rectangle.
And so on.
You have parallelogram
and various other predefined profiles.
I can go in and create
what's called an elongated hole or a slot as well.
Start point, end point of the center line,
and once again,
radius with my third point
or the size of the radius of the slot.
Some of these other predefined profiles are pretty handy.
Go ahead and play with them when you get an opportunity to.
Again, make sure you just follow along with the queue line.
For example, with the key way, this can be a little tricky,
so by making sure you actually follow along
with what the queue line is saying,
you can pretty much work right through it.
Select my keyhole profile.
Select your start point.
You'll notice down here it says select your start point.
Click my start point.
Define the center of the small radius.
So the center of the small radius
is going to be the narrow end.
I pick my endpoint, and you'll notice
that there's my small radius end,
and the fourth selection is going to be the large radius.
Once again, I have several pre-defined constraints
that come along with it.
You also have circles.
You can come in and create circles in many fashions.
Your standard circle operation
is just simply a center point and size.
You have three points.
Pick three points out in space to get a circle.
You have tritangent circles, three-point arcs,
three-point arcs starting with limits.
This is a very handy one.
We can select this and say,
I want a three-point arc starting with limits.
Let's just move the screen over a little bit.
Endpoint to endpoint.
So any time you hear limits,
it's always a start and end point.
A third point's always going to be
somewhere internal to the arc.
We also have splines and Connex.
We're not going to touch upon 'em here,
but if you feel like playing around with 'em,
please feel free.
And we have lines, several different types of lines.
We have standard two-point line, infinite line,
bitangent line.
So if I just pick on line,
I could select this endpoint,
draw up, and again, if I'm very cautious and careful
with where I select,
you'll notice I get an automatic tangent constraint.
I also have bitangent line.
I can select two arcs,
and you'll notice that near the points
of the arc that I specify
is where the bitangent line gets strong.
You also have creating points,
a point out in space, by clicking.
Pretty straightforward and simple.
The last feature I do want to mention is what's called axis.
What axis will do is it'll actually draw
an axis line for revolved features.
Works just like line.
You can either convert a line,
pick any line that you want and select it
and you'll get a warning message, saying,
hey, do you want to transform this into an axis?
Say yes, and there you go.
There's your axis line.
So that could become an axis of revolution.
Again, these profile tools, go ahead and play with them.
Pick around a bit, draw some curves.
They're pretty straightforward, nothing too difficult.
