SolidWorks is the world leader in 3D software for product development and design. Start creating manufacturing-ready parts and assemblies, as well as detailed drawings and bills of materials. In this course, author Gabriel Corbett shows how to create 2D sketches that will become the basis for your 3D models. You'll use the Extrude and Revolve tools to turn 2D sketches into 3D parts, then create more complex geometry with sweep and lofts. Then learn how to use the cut features to remove material and shape parts, and use mirroring, patterning, and scaling to modify parts. Next, you'll combine parts into movable assemblies and subassemblies. Finally, you'll create accurately annotated drawings, complete with itemized bills of materials that relate the final parts and assemblies to a manufacturer.
The Width Mate is a great tool to center one part within another. Many times there's not some type of feature like a plane or a face on the center of a part to easily center two items together. However, the Width Mate solves that problem. Also, the Tangent Mate is also a great tool to work with any type of curve surfaces. And we're going to go over both of those in this movie. To get started with, let's look at the Width Mate. So I have two components here, this one here, and this component here, and first things first, let's go up to Mate, let's choose this back face here, and we're just going to do a regular Coincident Mate here to bring those two components together.
Then what I want to do is I'm going to bring the two fronts of these together, so click on the front of this by choosing the face, not the edge, choose the face, and the face of this one, you can see the two components come together, using a typical, coincident mate, and that's all we want. Click OK. Now, what I'd like to have is I want this inside between these two faces here, and notice we've got a little bit of a problem. One is these are not the same angle. So, if I try to do a coincident mate it would fail. I could try to do maybe a little edge mate here to here. But that would make that touch, and again it wouldn't be centered.
So that'd be a problem again. So there's really not a lot of great ways to mate this and have this right between the center line of these two parts. That's what where the width mate comes in. So lets go instead of your standard mates, let's zip those up and come down here to advanced mates. The second tool with an advanced mate is called width. Click on that. And notice I've got two boxes here. I have the width selections and I have the tab selections. And what we are looking for here is two faces in each box. In this case here, I'm going to choose the inside face here.
And I'm going to rotate my model around. I'm going to choose this inside face here. Now, in my tab, I'm going to do exactly the opposite. I'm going to come down here. I'm going to choose the outside face. And I'm going to spin it around, and choose the other outside face. Notice, as soon as I do that, what happens is, it just makes the distance between here and here. And between here and here, the same. Click OK, and now we have a fully defined width mate. And, this part is perfectly in the center of these two, even though they don't have the same angles or shape. It's very handy for working with complex shapes, and getting things, centered up.
And, if I change this part, later in the future, it'll automatically update and always put it, directly in the center of the part. I'm going to spin it around here. And, take a look at another part. This case here, I have this little block. It's already coincident to the inside face, but it's floating around in space, and we need to define where it is in space. Now, I have a couple of options here. One, I could say, well, I want to make a distance. Choose a mate, I could say, from here to here. And I could say I'd like to type in a distance. And that would totally work but you have to calculate what the perfect distance is from that edge to make it right in the center.
And sometimes if the parts are going to be changing in the future, that will cause problems down the line and you won't get an exact perfect mate. Again, the width mate comes to the rescue here. So instead of this type of mate, let's cancel that, come back up to mates, jump down here to Advance Mates. Come up here to Width Mate and we're going to choose our selections. In this case here the width I'm going to choose the inside face here, spin it around, choose this inside face. For my tab I'll choose this face and my other one. I'm just picking those pairs.
There you are, you can see the distance from here to here, is the same as it is from here to here. And then click OK. I'm going to do it one more time. Click on Width again. This time, I'm going to choose the top face, bottom face for the tab, this face here, and spin it around, that face there. Again, it just centers it between the two. Click OK, and we've got a nice, fully defined, fully mated block, right in the center. Now what happens if I go back and change this block? Let's go Open Part. Let's take a look at that design. Notice it's three inches.
I'm going to change it to 1.5. Click OK. Exit out of the sketch. Go back to the assembly. And there it is. Perfectly made it right in the center. It doesn't care. The mates automatically auto adjust and it's perfect. You can also use the width mate with cylinders. Take a look at this one. I got this cylinder here and I want to put that right on top of that little block. Well that'd be pretty hard to do otherwise because there's no flat faces for me to mate together. Don't worry. Width mate's going to help us out. Mate, close up this, go down to width mate, choose a width mate.
In this case here, I'm going to choose the outside of the block here, and the other outside of the block, and for the tab, instead of choosing two faces, I'm just going to choose this one outside cylinder. And there it is. It mates it between the two. Click OK. Now I need to do that one more time, because it is mated right to left, but not up and down. So again, let's slide this down, choose the mate, come down to Width, choose the top surface, the bottom surface, and then for my tab, I'm going to choose that outside cylinder. There it is. Perfectly mated it, right on top of that block, with the width mate, and any changes to either one of those parts will automatically update.
Now I want to point out to use the tangency mate. Now, I have this cylinder here, and I have this piece here, which I'd like to be in tangent so that it can actually roll that outside of that cylinder. I'm going to click on Mate. First thing's first, I'm going to make a coincident mate between this face here Aand the bottom of that part. Go ahead and click OK. And now those parts are sliding around here. And I want to make this so it rolls around the outside. In that case here, I'm going to come down. Instead of Coincident, I'm going to click on Tangent Mate. I'm going to choose the outside face here.
And the outside face here, and notice as soon as I do that, when I grab that mate, I could actually grab that part, and roll it around the outside surface. This is great for wheels, or rollers, or any type of surfaces, you want to have them connected together but still have that rolling action of the two components. The Tangent Mate really is indispensable for working with any type of part with a round surface. The width mate command is very handy and solve mate problems that would otherwise lead to lower quality mates this is an advance mate and does take more system resources so only choose this option when simpler mate's just won't work.
