Primary pipe flange

00:00

Today we're gonna be creating this pipe flange that you happen to see on the screen. Now, even if you're not creating a pipe flange for your project, we're also gonna be learning some skills and techniques that you can use for whatever you're working on. So in this case here, we're gonna do a revolve, we're gonna do a pattern, we're gonna add some chamfers and some fillets and so on, and plus a whole bunch of other skills and techniques that you can translate or use for anything you're working on. So to get started, let's go ahead and just take a look at what went into creating this flange. So right over here, I'm gonna click on the items.

00:29

and it's gonna come over here to sketch one. You can see right over here, I've got a bunch of dimensions defining what that shape is. Then we take that and we revolve that around to create this body, right? Then once we've got that body, I'm gonna go ahead and create another sketch on the top of that, which is gonna define where all these different holes are. Then we're gonna cut those holes right through the flange and then come back and add some fillets and chamfers. If you look over here on the history bar, you can see here I've got my sketch one over here. There's that revolve.

00:56

sketch of where the holes are, we're gonna extrude those through, fill it up here, another fill it over here, and then finally a chamfer for all the top and bottom of those holes. So that's basically what we're gonna be doing in this project. So let's go ahead and take a look at the dimensions for this flange. Now this is a standard pipe flange, dimensions are available multiple different places, but I happened to have made a little cheat sheet for us. So we can go ahead and look at this slide show here. So that's what the flange is gonna look like. And here is the

01:25

dimensions of what the flange is gonna be. And right over here you can see that's the dimension of where the holes. So we're gonna start here and define what these dimensions are and create a sketch that looks a lot like what you see here on the screen. Let's switch back over here, back over here to Shapr. And let's go ahead and start a brand new project. All right, so right over here, I'm gonna get rid of these and just put them away on the sides. I want to start drawing something right from the beginning. So I'm gonna start a sketch. So here's my sketch.

01:53

And I'm gonna choose one of these surfaces. I'm gonna choose this one here, that first plane. And I wanna start with a center line. So I'm gonna start with a line. I'm gonna go directly up. The length really doesn't matter right now. And I'm gonna hit escape. Then I'm gonna go back to that line. I'm gonna say, hey, sorry, click on that line itself. Here it is. And I wanna say this is a construction line. That's why I wanna revolve everything around. Okay. Then come back, hit the L on the keyboard. So I'm clicking and creating yet another line. I'm gonna create this line out here.

02:22

and this is gonna define the inside of our shape. Now, the idea of this thing is gonna be 8.72, right? So I'm gonna click here first and then hit Escape. Actually, if you happen to have just clicked out of here, you can just click back on that line that's gonna show back up and then I can just double click on this and have the input here. So the diameter is gonna be 8.72. So I'm gonna say eight.

02:48

But I happen to be working in the radius. So I'm gonna say divide that by two and then click okay. And then I've defined that length right there. Now, of course I want this not to be a regular line. I want that to be construction geometry again. So that's defining what the inside is. Go back over here to the line command, come up here. I'm gonna define the height. Now notice because I'm going vertical here, the dimension or the length is changing. I can just, right here I can just type that in. So it's 1.75, right?

03:17

Hit enter there. And now notice that just shows up though it's stuck to my cursor and spinning around. And I want to make sure that that's actually locking to the kind of the vertical. So click over here and lock it to the vertical. Now I wanna head over this direction. In this case, I'm gonna not type in the dimensions. I'm gonna click here, I'm gonna click here, I'm gonna click out here, you know, back over to here, drop it down one and then back over here to the origin. Okay, now notice this little angle here, I made a mistake.

03:46

and it came in at an angle, that's okay, I can fix that. So if I click on that one, I can say, hey, I'd like this to be horizontal and that automatically fixes that, which makes it handy. And notice over here, this also wants to be horizontal, so click on that and that's gonna define where all those things are. Now what we wanna do is we wanna go back and start adding in some dimensions. So I'm gonna choose something from like the center line and come out here to this point here. So I'm gonna hold down Shift, pick that point right there and then define what that's gonna be.

04:15

Now that happens to be 5.31. I'm just gonna pull that information from my drawing there. So I'm gonna type it in, 5.31. Okay. The overall size from this line here, shift out here to one of these. Again, this dimension here. So that wants to be 13.5 as a diameter, which happens to be 6.75 as a radius. So 6.75 is my radius, defines that.

04:45

This spacing from here, here in, I'm gonna go ahead and just move that or I can see a little closer. So I'm gonna say from this line here. So I can say from that point there, hold on, shift to that point right there. Or actually, we could actually go from that line to that point there. And right there, that dimension here. Again, double click on it, 0.06. Okay. And now we're just kind of going around our shape and defining the things that we know. Something like this, just making sure.

05:14

It's always good idea to kind of make it a horizontal or vertical, sort of defining and just locking all those things in. How about the height of this? So from there down to here, so I can just shift and select something like that. And that's already the 1.75 here. And then this is the 1.2, which is not actually the right value. We need it 1.12. So I'm gonna click here and say 1.12. It's defining that. Now from my other dimension, I actually know the dimension from this point here.

05:43

over here to the center point. So if I click on there, I can define these. I just kinda like to space these out so we can see them a little bit clearer. And this dimension happens to be 4.845. So 4.845. Okay, and there that is. Now of course this got messed up a little bit. That's okay, I can just drag that back over here. And that looks fine. And the thing we have in the drawing is an angle here. So I'm gonna choose this line here, hold down Shift.

06:13

that line right there, and I'm gonna define that angle. So it has to be seven degrees from the vertical or in this case, 97 degrees. Okay, and now that's all looking pretty good, right? So in this point, you might wanna just click and try to drag something around. And so notice right here, it's like, I'm dragging you around, there's a problem. Why is this happening, right? Well, it's because we forgot to lock this point to the origin. So click on that, lock it to the origin. Now if I grab something and try to move it around, something still didn't work here.

06:43

Let's grab that point. Let's drag it over here to the origin and then say lock. Okay. And just make sure that that is locked. And now it should be locked in and we should be good to go. Okay. So now I have my shape. Now I have my axis of rotation. The next thing I wanna do is start doing a rotation, right? So right over here, I can go over here to tools and I wanna go down here to Revolve. Click on Revolve.

07:08

and says, what I wanna roll? Well, I wanna revolve that shape, right? And I wanna revolve it around that line. And as soon as I do that, notice what happens, it just gives me the revolve exactly what I'm expecting. So here's my revolve, looking pretty good. Click on done, and there's my first revolve, pretty handy. Okay, now what I wanna do is I wanna go to that top surface here and I want to start a new sketch. So click on sketch and I wanna put a circle. I wanna put it right over here. But before I do that, I'm gonna start with the line command.

07:36

snap to the center of this thing and define the value, right? So the value I'm looking for here is, is whatever that bolt hole circle happens to be. So in this case, the bolt hole circle happens to be 11.75 and I can actually type it in here, 11.75, but we're working on, oh, I got one too many. Let's go all the way back. 11.75.

08:03

And then I'm gonna say, I wanna divide that by two because I'm working with just the radius, click OK, and that's gonna define where things are. Now that line right there, I also want that to be construction. So I'm changing over to construction. And then I'm gonna go ahead and choose C for circle and draw a circle right over here. The circle I want happens to be 0.88. Hit Enter and there is my circle, pretty nice. Okay.

08:28

Now once I have that, I can then use this to do something else, right? I can create a 3D shape. I can use that to cut into my design. So here's my shape. If I spin my model around here, I can say, hey, I'd like to use that shape, and I wanna just push that right through the model, right? So here's my, I can just push it right through, no problem. Right, once I have that, hit Escape, or hit Enter actually. And then now I've got a hole, right? And I really wanna have more than one hole, right? But there's my first hole.

08:56

Now I can define, if I wanna go all the way through it, I can define the depth and things like that. And you can look over here under history and say, hey, that extrusion, how am I defining that? My distance, I'm gonna type something in. I can also say, hey, up to an object, that'd be okay. And then select the object. I can say, well, I'd like to use just probably the bottom of the part, right? That's okay. Click okay, and that's probably a little bit better defined. Right now it's just gonna go up to that next surface. And notice I've got the one profile selected. Well, what if I wanted to have multiple holes? I don't wanna go ahead and create and do that.

09:25

each time, that's a lot of extra work. So I wanna use some type of a pattern feature, right? So in this case here, if I go back to that sketch, right? If I go take a look at this thing here, not that, let's go that, okay? Over here are our items, right? Here's my sketch. So if I go ahead and take a look at that sketch, I can actually use some of the patterning tools here. So here's our pattern tools and I can find, hey, we're gonna wanna rotate this around, I'm gonna put that right at the center.

09:54

And I'm gonna say, well, I'd like to kind of pattern this little hole around this profile here. So instead of three, I actually probably want this to go through 360 degrees, right? So we're going all the way around and forward or backwards doesn't really matter. And then over here, as far as the amount, I'm gonna type in eight and there's my eight and that's looking pretty good, okay? So that is my updated pattern. Now what's cool about the history bar over here.

10:19

Notice we've only got that one hole. There's my hole, but now I've added to that original sketch a bunch of other holes. So if we go over here back to that extrusion, if I twirl it down, notice it's got one face or one for profile. I'm gonna go ahead and click on edit, and I'm gonna say, hey, I'd like to add a few more. So I'm gonna go and add these to the group, and notice as soon as I click on the individual profiles, it's automatically turning those into holes as well. So you can go back and modify those sketches.

10:47

so that you are able to create and expand the features beyond where they were originally. Okay, so right over here, things are looking pretty solid, pretty good. Next couple of things we need to do are the, we're gonna go ahead, I'm gonna hide that sketch, I'm gonna hide that sketch over here so we're only looking at the shape itself. Now we need a few radiuses and fillets. So let's go ahead and start right here. So if I hit F on my keyboard, it turns on the fillet or chamfer tool.

11:16

And if I choose this edge right here, I can then drag this in or out and kind of take a look at what it's gonna be. I want 0.252 for this, in this case, right? So there's my 252, looks pretty good. Click on the green or that blue check mark or check box or done and how about a couple more fillets, right? So this time I'm gonna try it again and I'm gonna choose like this edge right there. And this time I'm gonna, I know from my drawing that I'd like a radius of 0.

11:47

076, right, so it's added that, and click on that, looks okay. But hey, actually, I did notice that I wanna fill it more than just that edge, right? I wanna go back and change it. So right over here is that fillet. So again, I can go down here, I can say, hey, instead of one edge, I can go and edit it. I wanna say, hey, the inside, how about that one down there? The outside edge, I can hold down Shift, rotate my model around, I can pick this edge right here. How about this edge inside here?

12:14

All those, click okay, and now I've added all those fillets back to that same feature, right? So pretty nice and easy way to do that. Now how about a chamfer, right? So again, use that same tool. I'm gonna choose an edge like this one right here. And notice if I go one direction or another, I can go fillet or chamfer your choice, right? So you can go a chamfer this way, and I'm gonna type in.050 to chamfer that edge. Again, I could select all those edges ahead of time if I wanted to.

12:43

or I can go back to the Chamfer later on and say, hey, I wanna add some more. Right, so here's my edges. I'm just gonna go ahead and start adding edges to that Chamfer. So we have one feature and we're controlling all of the Chamfered holes at the same time, right? Of course, you could make a new feature for each one, but that would just be ugly and inefficient. So definitely wanna go back and edit and add the Chamfers, you know, all the edges, one feature. That way later on, if you said, hey, instead of a 50,000th Chamfer,

13:12

I wanted a 60,000 chamfer. You could easily just change that right here and all those edges will automatically be updated. So a couple of nice little tricks as far as making your tree or your history looking pretty clean, right? So here's our history. We got an original sketch right over here. We revolve it around. We had another sketch on top. We extrude that through. We had a big fillet, couple of small fillets and then chamfer those holes. So that's pretty much basically what it takes to build a part like this.

13:42

It's pretty straightforward. It sometimes takes a little bit of time to just define what that original sketch is and making sure you got all the dimensions. Of course, we pulled this from a database as far as a standard size pipe flange. But whatever you're working on, of course, if you're just creating something in free form, you can use whatever dimensions you want. But that's basically the tools and techniques you're gonna use to create something that looks a lot like this.
