- Ellipses, conics, and parabolas. Oh my.
Yeah, that's right. Let's get into it.
Right up here on our sketch toolbar.
Right over here, you can see, we have a icon for it
in ellipse and directly below that little twirl down there,
you can see we've got the ellipse, we've got a partial
ellipse, a parabola, and our friend the conic.
Starting up here with the ellipse.
Let's click on that one.
Click where you want to start. Click again
where you pretty much want to end.
And then third is you're going to be defining
whatever that width of that is.
So you're going to, click on the center point,
click on one edge of it and then finally,
you're going to define what the skinny part
of it, I guess, or the long part, depending how
you drag this out, click there, and then you have it.
Okay. If you want to define this a little bit better
I do recommend adding in a center line.
So come down here, grab a center line, snap
that center line from one side to the other side
and then notice we've got this horizontal relationship
which is pretty handy. But if you want to rotate it around
you can actually delete that, and come over here
grab one of these points, go ahead and anchor it down.
And then you can grab that other point
and you can rotated around that anchor point.
So you can do all kinds
of fun things with your friend, the ellipse.
The next thing we're going to look at is the partial ellipse.
So again, we're going to click where the center
point's going to be, to find one of the lengths,
and then of course define the other length.
And then the third option here is how much
of that ellipse we'd like to have.
So we can just kind of follow the profile
or the outline of it around to determine where it is.
Click when you're done,
and now you've got a partial ellipse.
Of course, we could do something very similar over here.
If we just took a regular center line,
cut it across our original ellipse,
and then we could come over here and trim the entities away.
I'm going to use the power trim
and trim this away here and trim that away there.
And you get pretty much exactly of the same thing,
but this one's a little bit cleaner.
Down here. We are looking at the parabola.
Parabola click here once where you want to start.
Here's our parabola kind of attached already
to my cursor so we can do all kinds of fun things with it.
And then we can define where we want to be.
So click again, and then third,
we can define which part of it.
So, it's kind of similar to the partial ellipse.
I can define, hey, I'd like to have this probably go way
up to here and defining it that way.
So that's how you would create that. And over here,
you can define all those variables as well.
And you can also switch over here to construction
if you'd like to, and then click, okay, when you're done.
You can also grab these points here and we can move them
around and adjust them once we've already created it.
And this little point right here allows you to move it
around this point over here allows you to stretch it out
or bring it in tighter.
So, a bunch of different controls we can do here
once we've already created one. All right,
And then finally, let's go ahead and take a look
at the conic. Conic, again, is very similar.
You're going to click once to start
and then you're going to drag out the conical shape
to however you want it to be.
Click when you're done, and then finally,
you're going to define what that row value is.
Right? So a few different values there.
So, place that conic, and then you can always come back,
again, and grab those handles and move 'em around
so you can adjust it after you've created it,
which is pretty handy. Same thing with the end points here
we can do all kinds of fun things with the shape.
Once you've created it, just grabbing these points
and moving these control handles around.
And of course we can also define all those things
when we create that shape originally.
You can also switch over to construction
like with all the other ones,
but those are the main controls and methods
for creating parabolas, conics, and ellipses.
