Learn about creating a couple of the sketches you need with the cupholder exercise.
- [Instructor] Here I want to get into some exercises. We're going to be designing this cup holder upper. Now this is the actual part, you'll have access to this part, you're going to download it. You can follow along using the actual data, but you're going to create your own geometry based off of this. So what I'm going to do is I'm going to make a new part. I'm going to go file, new, part, select OK, there's my new part. Now, for the sake of this course, I'm going to go ahead and do a tile vertically, so you can see the actual side by side and know exactly what's going on.
By doing so, I now have access to the appropriate sketches and sizes. So sketch number one, we'll get right into it. I'm going to double click on it here, and you can see sketch number one is going to be drawn on my XY plane. So I'll go into the part that I want to design on, I'm going to select my sketch icon, select my XY plane, everything's oriented just the way it needs to be, and I want to begin sketching out this profile. You'll notice that I'm drawing out half of the profile, getting it constrained, and then once I have that completed, I'm going to exit out and draw in my next sketch.
So let me just go ahead and expand my tree, go into my profile tool. Now as I draw this, I've talked about these blue help lines, they're pretty helpful in the context here, where I'm going to draw this first line as my center, and as I draw it, you'll notice that it's blue and it's constrained to my vertical axis. So I no longer have to worry about applying that constraint to that curve. You can see that constraint exists up there. Now the next thing I want is this arc, this line and this arc. So for this arc I need to come in here and say three point arc, point one, point two, there's my line, come back in, point to point.
Profile is closed off. Now I just need to apply these constraints. So I'll just come in, double click on my constraint icon, I want to pick this center line to this line. I'm going to right mouse click, distance, place that down, and this is going to be 43. I want these two to be tangent. Now you'll see I have 39, 39, and I have these coincidence constraints.
These coincidence constraints are the actual center point of the arc, a little difficult to see, but they're there, to this center line, right mouse click, coincidence. Do the same thing for this. Now, to finish off this sketch, I need to go 39 and 39 in either direction, to the center point, so taking my center point to here, horizontal to my center point on this end, and that is my first sketch complete.
So I'm going to exit out, and the next thing I want to do is, go to this other window, I'm going to exit out of the sketch here, and I want to hide this one, and show the next one. And as you can see, this sketch is built off of the same XY plane, so I'll come in here, pick my XY plane, select my sketch icon, draw out my sketch. Now, I'm just going to start out with a rectangle, once again I'm going to go right to the center, draw this guy out just like that.
Double click my sketch constraint icon, and start constraining. From my horizontal up, is 15, and this is where showing the original sketch is handy. What I'm going to do is, I'm going to pick this vertical line to this vertical line in the original sketch. That way I'm forming a relationship between the two, and now all I have to do is right mouse click, say coincidence.
So if the original sketch changes, this sketch will also update, modify, and change along with it. There is now a context within the design. That context is this needs to be the same size. Now that I have that drawn in, next thing I want to do is, I want to take these four curves and symmetry them. So, just as I did in the lecture, I'm going to do a trap, I'm going to pick these four curves, I'm going to come in here. I don't want to use symmetry, remember, symmetry will move them.
I want to use mirror. Select mirror, pick my horizontal, and these little icons here are indicating my mirror constraint. So those are the two initial sketches that we need to create my cup holder. The outer profile, and let me exit out, these little tabs. So now, I'll just exit out, and we want to make sure you save your file.
So just go file, save as, pick your location, give it your name. And done.
