Problem with welding

[Anonymous]

So I have tried to make a glass panel of car headlight by caping, extruding and so on. It didnt work, so I have created a spline from shape I need and somehow turned it into poly and now I am trying to weld vertices to the base. It doesnt work. Faces are flipped right way, object is attached back to base. Any idea? Thank you.

Hi,

Select the dark flipped polygons and in the Edit Polygons rollout

Click FLIP. Now, try welding your vertices.

Hi @miledrizk ,

all polygons are facing the same way and even when I try to flip them around, vertices wont weld.

Don't know if you already tried this, but it could be that you have to adjust the weld threshold.  Try selecting just 2 verts that you want to weld and cranking the threshold higher.  Another way to weld without worrying about the threshold is to use "Target Weld".  With that you just click on target weld and click on the first vertex and then on second vertex.

I have actually tried that. I used "Target Weld" and what is interesting is that cursor actually change as if it would weld, but nothing happens. Usually when polygon is flipped, cursor doesnt even change.

I thought you said that you verified that the polygons were not flipped?

But this leads me to another few thoughts:

Have you verified:

1) that there are no hidden verts (go to each Editpoly subobject mode and click unhide all to make sure) 

2) that there are not double verts on top of each other in the area you are trying to weld (zoom in and select a small area around the vert in question)

This is strange,

You said you tried Target Weld, but in case (assuming) your object is an Editable Mesh and not an Editable Poly,

You need to activate the Vertex Snap, then click the button labeled Weld, then click

On the desired vertex and drag it to the other vertex and release. This tool works differently in Editable Poly,

Where you can activate the Target Weld, click the vertex, release, and hoover over the other vertex

And click.

If this is not the case I suggest you upload your scene, so someone can check it for you.

I, personally, use Max 2018, so you need to save it as 2018.

I have checked with x-view for mupltiple edges, vertices, etc. Also I have unhid my whole scene. Nothing.

@miledrizk its editable poly. You can find model as attachement.

Weld works on naked edges only,

I highlighted the polygons that you need to delete to be able to weld your vertices

The outer edges will turn to naked edges after deleting those polygons and only then you can weld 

You vertices.

Ok, but I need those polygons there. The front polygon I am trying to weld will have glass material, so I cannot have holes behind it. I will try to delete them, weld and recreate them afterwards.

[miledrizk]

You can select them and detach them as separate objects

Didnt think of that. Thank you. Shame I have already deleted those polys 😞

Since you've been working on that for a long time I'm sure you have a recent version in the 

AutoBack folder. Generally it's in: C:\Users\yourusername\Documents\3dsMax\autoback

So maybe you can try opening one of the files, detach what you want and merge them into

Your working file.
