Test you SOLIDWORKS knowledge. This sample exam question covers creating mirrored geometry and building solids.
- [Instructor] For question number four of the sample exam, they're asking us to take this imported surface and the surfaces that we've created as well as this fillet over here and create the rest of the shape then turn it into a solid. So, the first thing I want to do is mirror over everything we have over here. We only have one surface body because we've already knitted it together so that makes it pretty straightforward and easy to mirror that over. Go over here to Features. Click on Mirror. The face or plane I'm going mirror it over is going to be the Front Plane right here and the Bodies to Mirror is going to be that one right there.
Click OK and there's the other half of the shape. Now, we need to fill in this section here in the front, as well as the one on the bottom, and I think doing the bottom is going to be a little bit easier. So, because we know that this is already on the Top Plane, let's go ahead and start a sketch on that plane and flip it around so you can see the bottom. Let's go ahead and just create a line from this point here all the way over to that one other there. That's going to then connecting those two dots together, which is our shape, and then, of course, we can also choose these other surfaces here, if we'd like to.
Choose individual edges around this perimeter. Okay and then go ahead and choose a Convert Entities. So, now, we have one continuous entity over here. Go over to Surfaces. Click on Planer Surface. Click OK and there's that shape and then we'll just do a Patch Surface in the front or a Planer Surface. Either one will work. Planer Surface is probably a better choice here.
Let's go ahead and just choose these edges here. That one, that one, that one, this guy here, that guy down there and the final two edges of this one and that one. You can see that fills in. Click OK and now, we have everything is one close boundary, we just need to knit them together. So, click on Knit Surface. I'm going to go ahead and choose this one here, that one there and that one there and I think we need to choose that one as well. Go ahead and knit all those together.
Now, we have one continuous surface body. Notice, down here we didn't have Create solid turned on or Merge entities. If we choose those two, click on that, now we have one solid body. So, very easily we have the ability to create a surface body or a solid body just by choosing these options under the Surface Knit. Once you get in, here they are. Create solid or Merge entities, we want to do probably do both of those things. Click OK and now we have a solid. The last thing we need to do is an apply a material of ABS. So, under here right-click on Materials.
Click on Edit Materials. I come down here to Plastics. I'm looking for ABS which probably the first one there. Apply that. Close that. Let's come down here to the Mass Properties and come down here to my Mass is 176 grams. Switch over and take a look at the Answer Key. I only have one 176.87 plus or minus 3.5 so we're definitely within the range and now we have the answer. So, those are a couple techniques for mirroring over surfaces, creating some more surfaces, knitting them together and then creating the solid and then, finally, creating this final body.
