Ok I did my best to try and do this on my own, but I can't seem to get to work the way I think it should. Ok. As you can see in my before image I have a nice edge there that I want to start welding edges togher to make it easier to edit the outer edge. Now when I weld the two edges together is flattens the outer brim. I thought that it would take the two edges and make them one edge. So I need some assistance. |

RJeff, think of the weld tool as a Vertex weld tool. So if you select an edge, it will bring the two ends together and weld them into one vertex.
BTW, you geometry looks illegal. Like you have faces inside your model. Also I think I see overlapping vertices. To fix those, set it to select through, then drag select over the vertices and weld them. Once you have gotten rid of the duplicate vertices you can delete the interior edges and faces.... but geometry like this may crash TS a lot. :( |

well Jack it will not weld vertexes. I moved the edges away from the other vertex I wanted to weld and it did nothing. I tried it several ways. I selected both the vertexes and then clicked the weld button and nothing. I also selected on vertex then hit the weld button and well it then deselected the one vertex I selected. |

That's probably because the resulting geometry would also be illegal so TS refuses to do it. If the model transfers over the bridge, you may want to use the Workspace tools instead. |

I dunno..I moved the vertexes I wanted to weld...and then I hit one vetex and then it flattened out the brim like I showed in the after image. |

Use Vertex select.
Hold Control key.
Select first vertice, then the second.
Click weld.
Jack is right, you might be looking for trouble creating single point geometry like this.
Scaling the edge very thin might be a better way to go- even paper has a certain amount of thickness. |

Yeah, something's definitely out of wack. You're probably going to have to delete verts and edges until you get rid of the bad geometry. Or just start that model over.
I've found that the workspace tools are much better at fixing bad geometry. Another thing you could try is the model side "Fix bad geometry" tool... ;) |

well what I did to get the model to that point was sweeping edges. That is the only way I could figure out how to get the shape that I wanted. I did the fix geomtery tool and it seemed to align the geomety right. I will just try to finish the model witout the weld..does not appear I can get it to work right. |

The weld function takes two points and makes them one, so you would get a sharp edge.
If you want to manipulate the full edge, try selecting polygons while holding down your <ctl> key which allows you to select multiple edges.
What exactly are you trying to do in this case? |

Ah I get it now! I know why the geometry isn't working for you. When you swept the edges, you swept them as separate extrudes instead of as a single extrusion.
Basically it's like having a bunch of fan blades sticking out instead of extruding out a contiguous ring.
To fix it, you need to delete the interior faces between the "fan blades" then weld the top two vertices followed by the bottom two vertices. To see if you welded them correctly grab a connecting edge and move it around to see if the model separates. |

Yes...that is it Jack...I do have most of the ones on the front of the brim of the helmetn swept at the same time. Then I had to go and sweep the rest one by one to get the shape that I needed. Now I want to weld thoes to the main part of the brim so I can make fine adjustments without having to pick 4 vertices to do it. |

Nothing to add, just like the topic name (weld(L)ing)
I'm guessing that "weldling" will be product you get when you complete the welding. :D |

Weld will only work on vertices that are already connected with an edge. In this case not all the vertices are connected with an edge, due to the way they were swept (each face swept separately, meaning you have two vertices at every location each on a separate face).
Fixing would take a lot of work and simply going back and starting over might be easier. The workspace is good at sweeping collections of joined faces all at one ("face loops" if you like) and may be your best bet in making this swept area.
HTH!

well I don't know how to use Workspace..guess there is no time like the present. |
