Creating a pipe accessory

- [Instructor] Let's make a pipe accessory. So what we're going to do is make a ball valve. Again, I know there's hundreds of them out there but this is how you make a pipe accessory. In rivet under families let's go new. Let's scroll down to generic model, click open. The first thing we do go to properties. Let's go to family category and parameters. Let's go down to pipe accessories. For the part type, for the value, click the drop down here. Let's go valve breaks into. Everything else looks good, click OK. Let's right click this reference plane. Let's create similar. On the draw panel click pick lines. For the offset let's go three inches. Let's go to the left. Let's go to the right. Now, let's go with one inch. Offset up, offset down, hit Escape a couple of times. In the measure panel, click the dimension drop down. Let's go to aligned dimension. Let's evenly space these. Let's go for the overall. Let's click a point here. Hit escape a few times. Let's click on the six inch dimension. Click on the create parameter button. Call it length, click OK. Hit Escape a few times. Now on the align dimension, let's go here, here, here. Pick a point off of it. Let's equally space that. Now let's click here and then here. Now the two inch dimension, click this for the label. Let's click create parameter. That name is going to be pipe size. That'll be an instance parameter, click OK. Hit Escape a few times. Next thing that we need to do is make a revolve. That's going to be the body of the valve. So let's go to create, let's go to revolve. The first thing I'm going to do is make some more reference planes. So go to create, let's go to reference plane. In the draw panel let's click on pick lines. Let's offset, let's say 3/8 of an inch. This will kind of be like the flange. I'll set this up. I guess let's offset it over to the right 1/4 of an inch. Let's dimension that. Click align dimension strong to weak. We can lock that. Let's dimension this strong to weak. Pick a point here. We can lock that. Let's increase the scale to inch and a half equals a foot. Oh, that's so much better. Hit Escape a couple of times. Let's go back to create. Let's go reference plane. The draw panel click pick lines and offset 1/4 of an inch, and offset this in. Let's dimension it. Go from here to here. Make a point like right here. Let's find our padlock way down here, lock it. Okay, good, on the modify create revolve tab. Let's click pick lines. Let's lock it down. And I pick here to here, to here, to here, to here and to here. And we've got to trim it out. Type tr for trim. This one to this one, this one to this one, this one to this one. I'm going to go with this one to this one and I guess we need an extra line here. Let's click on pick lines, pick this and we'll get a little error message. That's okay we can type tr for trim and trim this out. We can click pick lines. We can pick this line. Type tr for trim. Now I want to put a little ball here, right? So to do that we'll need a couple more reference planes. Sorry, so let's right click on this reference plane, create similar. In the draw panel let's click the pick lines button. For the offset, we'll go 3/4 of an inch. Let's go to the right, one to the left. Hit escape a few times. We'll dimension these. Dimension from strong to weak and we'll lock it. If we can find that padlocked way down here. But from here to here to that point, and we'll lock that down. Hit Escape a few times. These are in the way. So I guess maybe we'll just select this and move it up. Select this and move it up. It gets a little tight even at this inch and a half scale, huh? Hit Escape a couple of times. Now let's put a little arc in here. So I'm going to start on my arc start and radius button. Pick a point right here, and I pick a point right here. I'm just going to type in 3.5 inches. I'm going to hit Escape a couple of times. I'm going to type sl for splits. Make sure delete inner segment is clicked on. I'm going to pick a point here, then I pick a point here. Now we will have to dimension this. So let's go ahead and select the arc and click on this little icon here. Make this temporary dimension permanent. Hit Escape a couple of times. So we need to make this a parameter. We're going to click our 3 1/2 inch and click on create parameter, we'll call it bulb. We'll make it an instance parameter. We'll click OK. Hit Escape. Now let's put a formula for bulb. Let's click on family types. And for my bulb, I want that to equal pipe size plus 1.5 inches just to keep it consistent. Click apply, click OK. Now, we need to click on access line. So click on access line. In the draw panel, click the pick lines button. This will be our axis line right here. Hit Escape a couple of times. Let's click finish. Go to a 3D view, looks good. Let's go back to floor plan ref level. We kind of need a handle on this thing. And to do that, we'll need another reference plane. So let's right click on this reference plane and create similar. On the draw panel click pick lines. Let's give it an offset of two inches. and offset this down. Of course, we'll put a parameter on it. Click a line dimension, make a point from here to here. Point here, hit Escape a couple of times. Select that two inch dimension. Let's add a label, call it handle length. Make it an instance parameter, that's fine, click OK. Hit Escape a couple of times. Now let's go to create. Let's go to sweep. Let's click sketch path. Make a point right here to here. Hit Escape a couple of times, go to a 3D view. Click on finish edit mode. Click on edit profile. Let's put a little circle on there. Maybe a radius of 1/4 of an inch. We'll pop that little stinker right there. Hit Escape a couple of times, click finish, click finish again. Now, if we go to the join button on the geometry panel, select a little nozzle. Select your part and it joins are up. Now in the ref level let's see. Let's go to the front elevation. So go to elevation front. Let's go to create extrusion. This time let's set the work plan. Let's click pick a plane, click OK. Set it right to the face of that. Like we did before, I'm just going to draw a line out. I don't know, maybe two inches. Draw another line here, two inches. I'm just going to draw an arc like that. Hit Escape once, and draw an arc here to here like that. Now, the extrusion and I'll say 1/4 inch. It's not the fanciest handle, but it gets the job done. Click finish, hit Escape a couple of times, go to a 3D view. All right, so for the next video, we'll put some connectors on there and break it into a pipe.
