How to do a suture welding? - Polyloop

AlexGg · 22nd March 2006, 02:02

Gents,

I need create some suture welding between these two shapes(see below)
How to do that?

The number of vertices should match.

Pipe joints are generally not easy to do. The fastest way is to do a boolean union and leave it at that. Or just slid in the joining pipe without using any collision detection. If you are patient, you could draw edges or verts along the seam and support it by adding extra edges on the pipes.

Perhaps someone have some tutes for these kinds of puzzles. Puzzled Paul of Wings3d fame has some of his:

They're a bit tedious to do using other apps other than Wings3d. Perhaps someone here could help out. I'm interested to see some tutes, myself.

One of solution would be to use Bridge tool.
Like AlainK precise before, be care with the number of vertices.

Thank you AlainK for the link, there T-join looks like what I need! So I am gonna try to repeat it in the Hex...

You can boolean the cylinders together and then fillet the join (quick screenshots attached). You may need to add some extra verticies around the cylinders close to the join (see final model in the first image) as if you start with low poly cylinders, the fillet can be a bit coarse.

Smoothing the result a couple of stages gives an OK-ish result.

Yup, that's the most natural way of doing these types of modeling problems -- the boolean way. It doesn't have to be hard. Thanks... :-0

Guys!

Thanks a lot for the pointing in the right direction!
Below is my a very first attempt to use this combination:
Boolean -> extrude -> resize -> edgesTool -> smooth -> edgesMove -> Carrara render.
As I am new in hex I am gonna improve my result in this way. Once again, thank you guys!
Perhaps I have to write this tutorial...
