Learn the skills and tools for creating sketches that are the basis for 3D CAD files.
- [Narrator] Creating sketches is one of the fundamental tools inside of SOLIDWORKS. In this movie we're going to be covering some of the basics. The first thing I want to do is go ahead and create a brand new part, Click on OK, and to get started in a sketch, I have a couple of different options here. I can choose one of these planes over here on the left, I can come up here to the Sketch bar and click on Sketch, whole bunch of options. So in this case I'm going to choose something like the front plane. It doesn't really matter, you can choose pretty much any one of the planes, but I like to think about it like the top plane is kind of like the floor, the front plane and the right plane are kind of like walls.
So depending on the part you're designing, you might want to choose the plane that makes the most sense. If you're going to create a tabletop, I'd probably choose the top plane. If you're going to create a picture on the wall, I'd probably choose the right plane or the front plane, if that makes any sense. It makes a lot more sense when you start putting things together in an assembly, because the parts come in in the right orientation. But again, it doesn't really matter. You have the option to spin things around either way. The first thing I want to point out is, once you're in a Sketch environment, you're going to have these two icons up here in the upper right-hand corner of your screen. The first one is called Exit Sketch.
So when you're done with this sketch, you'd want to click on that button there and that will take you out of Sketch, but it will keep the sketch over here in the feature manager. If you click on that red X, it's going to delete everything you worked on so I'd generally recommend not doing that unless you're really sure you want to delete everything you just create. So, the next thing I want to do is I want to start using some of these drawing tools. So the first thing I want to point out is this Line command right up here. So with the Line command, I have a couple options. I can choose a point here and just kind of click around and create a shape.
If I close that shape, notice it highlights it in gray, showing me that it created an enclosed boundary, and I can extrude this into a 3D shape, which is great. So let's go ahead and do that. Go over here to Features, click on Extruded Boss or Base. Let's go ahead and just drag that out. Click on OK, and there is my 3D shape. Now let's go back and edit that sketch. So there's two things that are going on here. One is we have this feature called Boss-Extrude1, and that controls the depth of this feature. So I go over here and I click on it, I can come up here to Edit Feature, and I can change the depth.
I can make it a little bit deeper, but I can't change the shape of it. That shape is defined by the sketch. Click OK. Now if I want to change the shape, go over here to the troll down, and come to Sketch number one. Click on that sketch and click on Edit Sketch. Now I can change the shape, I can drag things around if I want to, and notice if I kind of go too far the lines start crossing. Now I don't have one closed boundary and it doesn't show up as highlighted which means there's an error. I can't extrude this. It doesn't know how to create this shape.
So I have to make sure that I have one continuous outside boundary. Now, if I add a circle or something like that, I can put a circle inside here which is called an island. If I exit out of that sketch, notice it puts that circle automatically into that feature. It just added it in as an island, but it's created the boundary between the outside of the circle and the inside of this perimeter. Now, I can also go back to that sketch one more time. This time I can grab that circle, and let's try pulling it outside and see what happens. Can you do that? Sure. I can create two individual features at the same time, or two different solids at the same exact time.
No problem. In fact, if you go over here, back to that sketch, you can create all kinds of different features. I can create more circles, I can create squares or rectangles, I can create polygons, anything you want. Exit out of the sketch and they all show up because what happens is is anything that's inside of the sketch is operated on by this feature. So this feature's just saying I want you to extrude whatever's in sketch number one by x amount of inches, And sketch number one is defining those individual shapes.
Now, if you make them overlap each other, for instance if you take this little rectangle here, I'm going to drag it over here and then bring this inside of here, it says well hey, this is a closed boundary inside of another closed boundary, so I'm going to create a shape that has this removed from this other shape. So you can drag things around and move them around. And notice everything here in our sketch is undefined. Everything's blue. It's not tied into the origin. If you remember those six steps, we generally always want to tie something into the origin and give it a fully defined size and shape. But, it's not required.
In fact, you don't need to do any of those things. I just highly recommend it, especially if you're creating a real part, but for illustration purposes I'm not going to define anything, we're just going to have to start creating some simple features and show you what's involved in creating your first parts and creating this sketch and how it all works. Exit out of this, then you can jump over here and create some more sketches. So click over here and start a sketch, drag a circle out or draw a circle out as needed, and go ahead and just cut it through. Do an Extrude Cut, or Extrude Boss.
Choose another one, choose another face, start a sketch. Let's try a polygon this time. Look's good. Features, let's extrude this one out. Drag it out, looks good. So you can continue building parts further and further out like this by just adding features from faces or planes, either cuts or extrudes, revolves, anything you want to do, we're going to be covering all those and how to do them as we go through the course, but those are all based upon this idea of the sketch feature on a face or plane.
So keep in mind, you got to choose a flat face, it can't be a circular face like one of these, it has to be a flat face, choose a sketch or start a sketch and draw out some geometry. Make sure it has an enclosed boundary or have two different boundaries that are on top of each other that make sense, and then just extrude that out. Now I want to show you one more use case. Now let's go ahead and choose the bottom of this part over here. Let's go ahead and start a sketch, and in this one I'm going to create a couple of circles. This time I'm going to make a circle here. I'm going to make another circle that kind of overlaps it. So now you have a problem because you have a double-overlapping contour.
So if I go over here to go to Features and say Extrude, it's going to say well, I don't totally know what you want me to extrude. So notice my cursor changed, I have this little icon with a hole in it, and what that's called is the Selected Contours icon. Over here you'll notice Selected Contours is highlighted and it's going to ask me what are the things I'd like to extrude? So if I choose this one here, notice it gives me this little half-moon shape. I can also choose the other shape and bring it all in or I can just choose maybe the intersection between the two. So I can select which of these contours, or part of these contours, I'd like to actually extrude out, and that gives you a lot of options as far as creating some geometry and how it all works together.
So those are the basic tools and methods for working with sketches and creating geometry inside of SOLIDWORKS.
First, see how to how to use the sketch tools to create two-dimensional sketches that become the foundation for 3D objects. Next, look at extruding and revolving 3D features; creating complex objects using the Sweep, Loft, and Surface tools; and modifying parts. Learn how to create uniform holes with the Hole Wizard, and explore more advanced modeling techniques using equations, mirroring, and pattern tools. Then review best practices for putting parts together in assemblies and building robust structures. The course wraps up tips for creating detailed drawings that relate the final parts and assemblies to a manufacturer, complete with an itemized bill of materials and drawing notes.
