T-junction join

[raw-m]

I'm looking for a discussion on this forum about creating a simple t junction but can't find the link. I'm trying to do a nice and simple joint, trouble is I'm getting a 5 point poly in the wrong place and can see the bend when sub-D'd (see attached) - it's driving me mental!

I remember about a year ago (possibly more) after much discussion someone came up with a really quick and elegant solution for a similar join - can anyone remember what/where it is?

Thanks

Beauty! Better than I remember.

While I love that video ;)

William has a great technique as well. :)

And of course the two mentioned videos rock! But there is also more info on this technique with some other examples in my tutorial.

Thanks Surrealist. Your site is a great resource and I often pass by your way, as I did with this to begin with (first port of call with anything sub-D'd). I must admit that I was put off a little by all the add edge commands for this particular shape - which sparked the memory about a similar technique on these boards.

Thanks again.

Well welcome to the world of subpatch modeling!

Add edges is your friend. :)

Also I describe a much simpler technique in that thread if all you want to do is create the join. No add edges involved. And if I remember correctly - Jeffry correct me if I am wrong - that is the same technique explored in the videos. Though it has been a while since I have seen them.

In any case in the thread I describe how all you need to do is line up the two cylinders, do a Boolean, merge points, and bandsaw pro, done.

The example in the tutorial is for more advanced modeling techniques. You have to look past the simple circle in the side of that tube to see that power of it for more complex shapes. And additionally that tutorial was more for putting the circle there to do other things such as this:

Add edges or other techniques are needed when you really need to stay with the contour of the host shape for the new addition.

I think your mesh looks cleaner than having the X in the mesh that I have seen and done for that matter.

Yeah, I don't think there are any 'add edges' in my video or in William's, but in mine there might be some 'connect' operations.

In a way they are all a little similar and it's probably a good idea to understand the concept of all of the different techniques so someone can decide what is the best for them for each use. I too like the end result of not having the X in the middle of the pipe, but I guess it all depends on the look you're going for and how close you'll be viewing the pipe joints.

Hah ... All I saw was "T-Junction join" and I already had my fingers typing out Surrealists tutorial link... damn I'm slow this week. Glad it worked out for you.

One tool I find invaluable for tightening subpatch surfaces is FI's wrinkle tool. If I have an edge that I want to tighten up, I select its points, then hit wrinkle. I set the Depth to 0, and that gives me a nice smooth join. It's basically adding points around the join. It always makes quads too, so it's really good for subpatch modelling.
