What is the C0 property of a weld?

What is the C0 property of a weld? I know the value is a CFrame but I do not know what it does. Does the C0 of a weld affect the Part0?

Try checking the developer.roblox.com page. There are lots of answers and a lot of information there like all the parts of a Weld | Roblox Creator Documentation.

I have already read what the C0 is on the links you sent me and I am still confused. Is the Part0 of a weld positioned at the C0 of the weld?

It’s probably best to use a WeldConstraint | Roblox Creator Documentation so you can see how the Weld is set up.

You can visualize C0 as an attachments CFrame like this post below:

Combining Models with respect to their attachment CFrames

Hey There! I’m trying to move one model to another model so that the CFrame of the first Model’s attachment matches the CFrame of the second model’s attachment. (Here I’m moving the red Model with respect to the blue model’s attachment) Before: [image] After: [image] Video To Explain: https://gyazo.com/70ed29211f7b28c71d845cacd8ea1a0f I know how to do this with Position and Orientation values with BaseParts, however I’m not sure how to make this happen for models with CFrame. Thanks f…

Because the math is similar.

Attachment.WorldCFrame = Part0*attachment.CFrame-- find the world CFrame relative to origin axis.
--similar to
OffsetCF = Part0*C0
OffsetCF = Part1*C1
--weld is when the offset CF is the same so
Part0*C0=Part1*C1
