Complete building the cupholder exercise using the original as a reference.
- [Instructor] So here we're going to finish off the cup holder we started earlier. We're going to come in, going to go to pad one, right mouse click, define our work object so we can see what it looks like. We're going to double click on it, check it out, 19.25 millimeters, and it's going to be going in the negative Z direction. So let's cancel, click in the window we want to work in, select pad icon, reverse the direction. Remember, negative Z. 19.25.
We'll do the same thing for the next pad define our work object. This is going to be, again, negative Z, 30.5. So we'll click in the window we want to work, create our pad, select our sketch, reverse, 30.5. Next, we're going to add in our drafts. So we'll just go to draft two, right mouse click, define our work object so we can take a look at 'em. First draft is going to be this outside wall. I'm going to double click on it.
My neutral element is this top element. Remember, it's the blue one, and the faces I want draft to the side, so I can pick this center face and the others will propagate and select automatically. Come in, select my draft, faces to draft is this one. My neutral element. This top face. We'll go to one degree and preview. You can see it wants to draft out. We want to draft in, so we'll just reverse the direction. And select okay.
Draft two, these four side faces here. Just double click on that, see what the parameters are. You can see here that this face is my neutral element, and these side faces are the faces to draft that two and a half degrees. And again, draft is negative Z. So, let's come in, pick my draft, faces to draft, neutral element, select my neutral element, enter in my draft angle, and okay.
Next, I have an edge fillet and a shell. So I'll just go down to the edge fillet, right mouse click, define our work object. You can see it's these four edges. I'm going to double click. Two millimeters. Select the window I want to work in. Select my edges. These four off of each side. Two millimeters and oop, I missed one, so let me just double click on that and add it back in.
Now that I have my edge fillet, I'm going to go into my shell, define my work object. Double click on that to see which faces are going to be shelled out at 2.9 millimeters. My shell function. Enter in my thickness. Next, I have pocket, pad, so I'll just go down to my pocket, define a work object.
That's going to be removing these faces, so let me hide/show that sketch. On my XY plane. Enter in my sketch. And let me go ahead and double click on this so we can see what we're working with. We'll come back into this window, draw in my rectangle, And as you can see, I got 1.75 mils off of this edge coming in, and 35 up and down. So I'll go ahead and constrain that.
Exit out of my sketch. Come in here, exit out of this sketch, and verify the size of this pocket. So I'm just going to double click on it. And as you can see, the first limit goes all the way past through the part. And it's currently at 66. The second limit is up to pad face, and as you can see, it's this bottom face off of the slip. So when I go up to plane, I can just pick that face and the pocket is going to stop at this face.
Now remember, pad and pockets work exactly the same, except for pad adds material, and pockets remove material. So we'll come in, activate the window, go to pocket. This is going to go down to 66. Select more. This is going to go up to plane. Select that face. And select okay. As you can see, I have my little ears carved out.
Next is another pad. Define a work object, double click on that sketch to activate it, and it's this outer edge. So I'll go into my XY plane. Select my sketcher tool, and to draw this, pretty straight forward. Just go into profile. I'm going to start out with a three-point arc. And just get it kind of close to where I need it. Doesn't have to be precise. Remember, you're going to go back and constrain this.
And then the next arc is going to be a tangent arc, so I'm just going to click and drag. Remove my finger off the mouse button, and finish off the arc. Exit out of that profile and constrain it. Double click on my constraints. I'm going to take it, go from this point to this point. Right mouse click, coincidence. Same thing on the bottom. And then take these arcs and line them up.
Exit out. Come in here, do the same thing, exit out, and verify the size of this pad. Double click on it, and as you can see, I have nine, two, 0.5, 0.25, and this is going in the positive Z direction. I'm going to go ahead, create my pad, select my sketch, and again, this is an open profile, so it's going to give me this invalid profile body.
I'm going to select okay and turn on thick. It doesn't always tell you how to solve the problem, so you every once in a while have to really understand what's going on, so we know it's an open profile sketch, so you just have to go in and turn on that thick. So this is my nine. This is my two. This is 0.5. 2.5. Positive Z direction, select okay. I have a hole to find a work object. I'm going to double click on it.
4.6 up to next, so we know what's going to go through the part. It's going to sit on this outside face. It's going to be countersunk with a depth at an angle. So we'll come in, pick my face, we'll go to hole, 4.6, up to next, type, countersunk, depth at an angle.
1.5. Preview. Now the next thing I need to do is get the position. So I'm just going to select okay over here. I'm going to come back to my hole. Double click on that, and go into positioning sketch. So this constraint is locking it down to my ZX axis or ZX plane, so I'm going to go ahead and use that, and it's five millimeters down from the top. So I'll just go back into this sketch over here. Constraints.
There's my ZX. Coincidence. From the top, down, five mils, exit out of my sketch, say okay to the hole, hole has shifted into its correct position. Now, I'm going to come in, and this is something that I've seen quite often in the past. I'm going to right mouse click, define a work object down the mirror function.
We have extra features in the tree sometimes that are absolutely unnecessary. And since I haven't had a chance to really talk about the delete, I'm going to right mouse click over the feature, and we're just going to simply say delete. Little delete window comes up, you sure you want to delete that? Absolutely. So at this point, you're not going to have that extra feature in the tree, but if you happen to have an extra feature in the tree, you can simply right mouse click over something, and hit delete, and away it goes.
So, the next step is a pocket. Define. I'm going to carve out these little holes, come in, hide/show this pocket, sketch, click in the window I want to work in, select my sketcher tool, draw in my rectangles, go ahead and activate this.
So as you can see, I have the dimension from the bottom, each side, and the height. Once again, just simply constrain it from here to here. Let me get this out of the way. There's a point right at this vertex. I'm going to pick that. Going to come in, and my height.
Now I know I need this on the other side, so I'll just grab these, do my mirror, cross my vertical axis, exit out, make my pocket, and for this, I'm just going to reverse the direction, and say up to last. That way, we know it's going to cut through. And to finish it off, we're going to go ahead and use that mirror function.
We'll select mirror, select my YZ plane, select okay, and complete. Now when I come over here, I'm going to exit out. I expect to see something very similar. So just come down to mirror two, define a work object, hide the sketch, and for visualization purposes, you can just trap those planes and hide them. And you should see something nearly identical. Maybe the color will be a little off, but that's about it.
