Merging pipes

Hello,

I've been stuck on this for a while, tried different techniques and this is the best version so far. I'm trying to get the pipes to merge, right now theres a hole where the 3 pipes meet and they collide on the inside. Would love some advice!

    You may want to look into the "frame"command. Here is a link to a sample of your type of part (not to scale)

    Using frames will require some "getting acquainted time", but I think you can see it's a pretty light workflow (do a section view on the top plane). There are probably half a dozen ways to model this part, this is just one idea. You could just sweep a solid, then shell.

    If you need to have it at that angle. then I suggest a sketch plane on that construction line. like this and redefine sketch 3 to use that new plane. like this.

    Here's another that turns out pretty simple. My thought also was frames as soon as I looked at this. Ended up trimming the joints as 3 pieces because I was thinking of tubes, UUHH!! When I clicked that it's 3D print as one part the method got a lot simpler with offset faces and a thicken still using frames for ease.

    Maybe a bit late to the party but doesn't this do what you want?
    I only needed one sketch and 3 features using the profile sweep but you would only have needed one more sketch to do with regular sweeps.

    These kind of things are always easier to make solid first and hollow out with a shell at the end.

    Are you able to clean this angle up? or does it have to be at that angle?

    @MDesign Thanks for your response! No, these angles arent necessary, to be fair with you I made it like this so the two pipes would end up relatively flat, one headache at a time haha.

    Is this to be 3D printed? - Scotty

  • maurice_biermanmaurice_bierman Member Posts: 6

    @rick_randall Thank you as well!! That model is something I can work with, amazing. Thank you so much for showing me how to use frames in this instance! And yes, this is meant to be 3D-printed :)

    Maybe late to the party but still very welcome! Thanks for showing me more ways to achieve this, I was really struggling with making pipes, you have given me so much insight in how to solve these dilemmas now, thanks a lot! Love this community!

    If there is general interest in a 3-way joint creation tool please file an improvement request. I've encountered this a few times from tickets and have tinkered with various custom features to do the job but want to track general interest. @jnewth_onshape
