Joining Pipes with Intersect - Skill Builder

so a few weeks ago we released a skill builder showing how to punch holes in tubes which of course led to the question well how do i merge two tubes together we'll do that with this guy in this week's skill builder [Music] so last time we looked at using solid tools to punch holes in tubes different different holes we made like just holes go all the way through partially through tapered holes holds the chain shape this time we're going to take a look at something like this and how we would use intersect to actually join the two tubes together so let's let's hop right in okay so as i look at this i have these two they're not currently groups um they are both solids so it would be possible to punch a a hole through one with the other using regular solid tools but that's not what i want to use i'm actually going to use just regular old intersect with selection so here's what i'm going to do i'm going to start by grabbing this tube and i'm going to move it so i'm going to grab my move tool i'm going to slide it right in and i'm going to slide it so that it goes into so that see that end is fully inside the tube all right so now this point what i want when i'm done is basically one solid piece that is a big tube here and then has a tube growing out of it basically but the opening on the inside should go through to the opening here and as i look down here i should see an opening all the way down with a hole in the wall so i want those to join together so solid tools actually is not the ideal solution for this what solid tools will do is it will cut a shape that is similar to this out of the two pieces it could join the two pieces together which would leave me this extra geometry inside i'd have to get rid of so there's ways to do with solid tools but it would be extra steps because i'd have to break geometry twice i'd have to maybe copy some geometry and move some geometry so there's a simpler solution and that's we're looking right now so the first thing i want to do it's actually going to be two intersects the first intersect is going to be exterior so i'm going to select this tube right here i'm going to shift select this tube right here so i just have the extra if i look on the inside no selection no selection just these two exterior pieces then i'll hit the right button i will say intersect face with selection and there we go it breaks it if i look inside it's still lapping over itself inside here still lapping okay so this is good this is actually where i want to be right now by choosing intersect with selection i'm only saying only these two faces intersect each other so now i'm going to do the same thing on the inside so i'm going to rotate so i'm looking inside i'm going to grab the inside of the small piece shift select the inside of the bigger pipe right click and again intersect face with selection and that's going to break it so i'm going to i'm going to do some fancy 3d mouse work here we're going to dive inside and take a look so there that broke that piece right there where it hits this so now we got to do some cleanup um out here on the outside we want to keep this but if i look through here i want to get rid of that so i'm just going to select that and delete it that's the exterior shell leftover piece and then here's the interior shell left door piece i'll delete that also now i'm going to spin to a top view and what i want to get rid of now is all of this so just by doing that select window i got the end of the pipe and the exterior and interior the pipe if i hit delete there look what we got this is exactly what i was hoping for so we have our full pipe here with a hole here it joins on the exterior it goes all the way through and we basically just made a t-joint if like a pvc or something like that but it's one solid piece the openings on the inside the joining is on the outside and we just did that with two i know i talked a lot and it took longer than it should but that's kind of what i do we did just two intersections extra intersection interior intersection and then we erased the leftover pieces so let's let's do that one more time let's go hop over here got some more pipes these two pipes are exactly the same size so when i slide this guy i'm going to triple click this i'm going to start sliding it over and it's going to disappear into that pipe now this is a little bit different from what we did before because if i just if i want an x i could actually cross all the way through and do that same intersection work but i'm going to say i want it just to t so what i want to do is i want this piece to hit directly in the middle of this piece so to do that i'm going to show my hidden geometry let's give me my lines i'm going to grab it by this point right here and i'm going to pull that full thing in i'm going to stay on the red axis come across come across come across and i want to stop boom right where it intersects there this is one of the ways you can use intersecting geometry you can use that hidden geometry to find intersections like that to do my intersection node actually intersects with selection i do want to turn my hidden lines off because that's going to make it a lot harder to do so i'm going to start do same thing exterior grab my two pieces right click intersect face with selection and we get that interiors same thing grab my interior interior right click intersect face with selection so even though my exterior crosses over my interior it doesn't matter because by running the intersect with selected it only chooses to see the pieces that are actually highlighted so i'll do the same thing here i'll go to the end delete this piece go here delete this piece i'm now looking the inside let's look down from top all right let's grab that delete it oh i got a little extra geometry little little extra extra geometry all right and there we go check that out so this on the x exterior it's joining right at the edge if i look at the interior it's going all the way through and that one was a full t-pipe of two pipes the exact same size and we can actually you can come back over here we can hang out together so there you go again this something like this could be done with solid tools you could actually uh create the intersecting faces create the geometry where they overlap and take that geometry and merge it into the solid groups to break them and then put them together it would just be a lot more work what solid tools can't do is say okay only take this face and intersect with this face while this face only intersects with this face and that's exactly what intersect with selection does it gives you the chance to select which faces intersect which and then you do have to go through and just get rid of your extra geometry i hope you liked that video if so click like down below and if you haven't already please subscribe we create several videos a week and you'll be notified of each and every one of them and
