Creating a Y-Piece with tapered ends

[Anonymous]

Hello everybody,

I am totally new to CAD and Fusion 360 in general, but I have tried to gain some knowledge with the help of tutorials.

I would like to create a Y-piece with two tapered ends for pipes.

I have created the first part of the Y-piece with the help of the path and pipe tool. After that I created the tapered end for this part. I then mirror the whole component, but when I investigate the outcome, I have quite a lot of collisions (which does make sense due to the mirroring).

Can you tell me how to get rid of this collisions? Does these collisions happen already because of the way I am creating everything or can I remove the collisions quite easy afterwards?

Here is a link to the project as well.

I would really appreciate some advice.

Kind regards

Michael

Hi @Anonymous

Could you please explain what you mean by collisions?

Hey @beresfordromeo,

by collision I mean that the mirroring does cause interference at the joining point of both pipes.

I have made a screenshot which shows the interference a bit.

Can I cut the body maybe with the help of a sketch?

Hi Michael,

Here is a suggestion on creating this geometry.

1. Sketch the V shape and the two straight segments on either side of the V.

2. Sweep a circle using the sketch as a path.

3. Create an offset plane for the length of the tail of the Y from the vertex of the V.

4. Extrude a same size circle "To Object" and select the swept feature from the previous step.

5. Shell the caps.

Hopefully the above is clear to you, if not let me know and I'll add a screencast.

Best regards,

Sanjay Jayabal.

Hi Sanjay,

thank you very much for advice! I have tried what you have suggested and recorded it. Is this what you meant? http://autode.sk/2lD7MUK

It looks pretty good! 🙂

Btw: I have found this as well: Create a T-Spline pipe. But I do not understand how a Y-Path is created. Your solution is absolutely great, I am just curious because the other solution uses the pipe tool command afterwards. I have tried to create a Y-Path, but I cannot connect the single lines to a Y.

Best regards

Hi @Anonymous

Well obviously others have suggested methods so I guess there are those as options bit if this is the shape that you require you could just combine the bodies to form a new component.

Here is a quick screencast about how to do this.

Although this is possibly the answer to your specific question I am not sure however that this is the actual design you are looking for. The place to start is to work out what you want the model to look like. That is to say do you want these sharp transitions on these tubes etc?

Hey @beresfordromeo

thank your for working out for me how the combining works. I have learned a lot today and this is due to all the good advice you all give me!

Actually, I do not want these sharp transitions. But I played around with the Fillet-Tool a bit and it worked quite finde. Or can you recommend a better way to create nicely shaped pipes?

Kind regards

Michael

Hi Michael,

Attached are a couple of screencasts.  The first one is modeling it the way I described earlier and the second one uses Pipe.  In the pipe workflow, note you can also window select the entire sketch and call the Pipe command.

Hope this helps.

Best regards,
Sanjay Jayabal.

@Anonymous here is how to do a "proper" Y-Branch using T-SPlines:

Hi @Anonymous

No problem at all. Always a pleasure to help a fellow Fusion 360 enthusiast and I always find doing so is a great opportunity to learn also.

When you say you 'played about with the fillet tool', did you fillet your sketch path or the pipe bodies you created?

There are lots of ways to create smooth shapes in Fusion, pipe included but the method will often depend on the intent. This is a very important part of using the tools, knowing what you want to achieve. Hopefully the great examples from @sanjay_jayabal and @TrippyLighting will help you get started but if you have further questions please feel free to ask.

Thank you for all the great videos. It is quite interesting to see how many ways there are to create this y-piece. I am already a bit confused as well. 😉

@beresfordromeo

"When you say you 'played about with the fillet tool', did you fillet your sketch path or the pipe bodies you created?"

I think, I fillet the pipe bodies. (I have marked it in the sceenshot). Does it make big difference?

[beresfordromeo]

hi @Anonymous, you are most welcome.

Ok well, for sure it can make a big difference. 

I have recorded a video for you that shows how you can do this but also try out the suggestion of @sanjay_jayabal which is also a nice workflow if that is what you want to do. As I always say. the tools used are mostly the consequence of your intent.

For the example below do the following.

1. Look back in the timeline at the bottom of the screen, right click and select edit sketch

2. Use the sketch > fillet tool on the sketch of your pipe path.

3. When you have done this right click on pipe along path in the timeline and click on edit feature.

4. Reselect the path as you see in the video below and click OK.

Best of luck, let me know how you get on.
