Grid Fill causing corner bulges even after subdivision – how to fix?

[Deb kanta Guin]

How do I fix this issue? After using Grid Fill I’m getting this bulge at the four corners. If you look carefully, you can see it, and even after applying subdivision it’s not getting fixed.

Hi Deb,

You can try this: in Edit Mode, SHIFT+ALT+S > To Sphere and then Move your Mouse to the right (or just press 1).

After that, you’ll have to use Proportional Editing again, to get the ‘bell’ shape back.

However, it is probably better to not use Grid Fill for this; Grid Fill works best for flat patches. Concentric rings will work better, something like this:

Usually with subdivision you want a holding edge, so in your case, like Martin says, you need a circle around your perimeter with the same shape to hold things together. You want this extra loop:

So that these guys are not in your perimeter pinching your mesh:

Ahh, I forgot about that… it was actually taught in the mesh modeling classes. Thank you, Omar, and also thank you, Martin.

Can you help me with this curve? I’m not very fluent with curves, and the wire shape is getting broken

[Martin Bergwerf]

Hi Deb,

Don’t know what you did wrong there:

Did you Scale the Curve in Object Mode, maybe?

[Deb kanta Guin]

@spikeyxxx I just came back to say that I didn’t apply the scale. I actually didn’t know that it needed to be applied — I don’t think it was mentioned in the tutorial. Anyway, it’s better to discover some things on your own, because that way they stick in your mind forever. Thanks a lot for answering my question so quickly!

Is there any way to connect the wire and the lamp properly…because manually if i adjust the lamp and place it to connect the wire its not looking good.

[Martin Bergwerf]

A tip for the furture:

Do not Scale Curves in Object Mode!

With Meshes, you can Apply the Scale, when you’ve Scaled in Object Mode, to get the same result as if you had Scaled in Edit Mode.

But Applying the Scale of Curves, can really mess things up.

To connect them, I would Adjust the Curve, not the lamp:

Hey @spikeyxxx, I’m sharing my project URL — could you please check it? What I’m trying to do is make the objects watertight like the wire stand part connect with the base and the lamp, so they’re joined properly. But just pressing Ctrl+J doesn’t work. If you could help me with that, it would be really helpful and I’d learn something new. Thank you!

And also, thanks a bunch for the tips!

ALT + J isn’t working because one is a mesh object and the other is a curve. You have to convert the curve to a mesh. You have to go to Object -> Convert -> Mesh. 

[Martin Bergwerf]

Yes you need to Apply all Modifiers, then you can Join them. If you try to Join them now, all Objects get the Modifers of the Active Object and thet is not what you want.

Easiest way, Select all the Meshes, then Object > Convert > Mesh to Apply all Modifiers. Then CTRL+J to Join them.

[Deb kanta Guin]

Thank you so much, both of you.

I totally get the point, and yes—I didn’t convert my curve to a mesh, but that’s not the problem I’m facing here. You see, I’m not just saying “join the objects,” but when I press Ctrl+J, it doesn’t actually look like it’s the same object. I want to blend them to look like it’s a same obj.

I tried using the Bool Tool after watching a YouTube tutorial, but it’s not working properly—it doesn’t look very good. That’s why I’m requesting: could you please check it? I shared the link—just give it 2 minutes and please tell me what the problem is.

I really appreciate your help, Martin and Omar.

[Martin Bergwerf]

Okay, 

Delete all Subdiv Modifiers.

Select all Objects apart from the Curve and Convert to Mesh.

CTRL+J to Join.

In Edit Mode, connect everything.

You will notice, that your ‘wire’ has way too much geometry to work with, so you should go back and re-make that.
