Join Gabriel Corbett for an in-depth discussion in this video Sketch Tools, part of Cert Prep: Certified SOLIDWORKS Associate.
- In this example you're going to see a modified part using some sketch tools. So what I have done here is I've created this hole in the side of the part. Now this is not a shell, it's actually just a cut, and I use an Offset Entity, and a couple other Reference Geometries to create this. So let's go ahead and see how we create this one part here, so I'm going to open up 2.2, and click on this face here, and go ahead up here, and start a sketch, you can start here or you can just click on the face and click on sketch. Alright, now while I'm here, I want to use all these lines around the perimeter here, and a quick way to do that is just click on the face, and click on Offset Entities.
And I'm going to say one millimeter, so 1.0, and I want to reverse that so it's going on the inside, and then click OK. That just converts all those entities and brings them in. Now the same thing here, if I want to use Convert Entities, I can say convert it, if I have a converted entity, then I can offset it as well, and just say Make base construction. So either way works for that. Now to create the lines, I want to create a center line from the top edge here down to there, and then I'm going to use a line all the way across the part. So I'm going to make a part from here all the way across over to here, actually to this line right here, and I want to make sure it's hitting that center point, okay.
Coincident, and make that Horizontal. As soon as I do that notice it's not hitting over here and I'm going to bring this little point here so it snaps onto that line. So I'm using a center line to lay things out, as well as Offset and Convert Entities. From there I'm going to make a line directly down, make sure it's vertical, and then I'm going to use my Trim command so Trim, I'm going to trim all this material here away, and this little corner here just using Power trim, just drawing through those lines, and this line right here, again, I'm going to trim this material away, so that's the piece that I'm going to be cutting away.
And the same thing up here, I'm going to trim this away, trim this, and these two surfaces here. As soon as I do that, I am now ready to delete this as well, hold on, let's go back. I don't want to delete that because it makes everything blue, so let's just go ahead and make sure it is for construction. Once we have that, I can go Features, Extruded Cut, and notice it's not automatically giving me a piece to cut away, that's because there's a dangling line in here.
Somewhere there's a line that's keeping this from being a full cut all the way through the part. Now I can choose a feature like this that says it's only going to be a selected contour, but I generally try not to do that, just because I want to make sure that my sketch is complete. So I want to just verify around the outside of the sketch that there's no dangling dimensions, and I'm thinking the dimensions are probably going to be somewhere in this region over here, or somewhere up here on the top. And there it is, alright, so that little piece right there, I'm going to delete that, make sure that that's not there, that way, when I come back, I can say Extruded Cut, then it works, and then I'm going to say, instead of Blind, I'm going to say, Offset From Surface, and this again is going to be used quite a bit in the exam.
So Offset From Surface, I'm going to choose the surface, which is going to be the back, and I'm going to make a 1.0mm spacing, and then click OK. This same type of part is going to be done multiple times in the exam. It's going to be some kind of modification to an existing part, and some type of a shell type feature or some type of a cut using existing geometry. So Offset Entities, Trim and some Construction Geometry like center lines, is really going to be a helpful thing, so make sure you go through and look at these sketch tools here, especially the modification tools, like, Trim, Offset and Convert, because those are really going to be used throughout the exam.
Along the way, he'll cover creating effective sketches, using equations to modify parts, weighing parts, building assemblies, assigning the correct materials and units, and creating drawing views. At the end of the course, there are two sample exams to practice what you've learned.
- CSWA requirements review
- Working with sketch entities (Line, Circle, Rectangle, and Arc)
- Making offset, convert, and construction lines
- Reviewing the boss and cut features
- Sweeps and lofts
- Smoothing corners with Fillet and Chamfer
- Creating linear and circular patterns
- Dimensioning techniques
- Setting mass properties
- Selecting and using materials
- Inserting components
- Setting up reference geometry
- Establishing standard drawing views
- Annotating your drawings
