Rotating part affects all welded parts

[Mr_Spokes]

Might be pretty simple, but I am unsure of how to rotate a part without affecting all welded instances and keeping the welds.

I’ve been able to set Part.Rotation with only that part rotating, and still staying welded together.
How are you rotating them?

[Mr_Spokes]

I am using a more complex method since I have to use the pivotpoint in this specific situation:

script.Parent.Doors12.Door1InIn.CFrame = script.Parent.Doors12.Door1InIn:GetPivot() * CFrame.Angles(math.rad(90), 0, 0)

Took me a while to figure out to get the right result. However not sure it’ll work correctly for your use case, but seemed to be consistent with a basic test on 2 welded parts.

local newCFrame = script.Parent.Doors12.Door1InIn:GetPivot() * CFrame.Angles(math.rad(90), 0, 0)
local xRotation, yRotation, zRotation = newCFrame:toEulerAnglesXYZ()
local rotation = Vector3.new(math.deg(xRotation), math.deg(yRotation), math.deg(zRotation))

script.Parent.Doors12.Door1InIn.Orientation = rotation
script.Parent.Doors12.Door1InIn.Position = newCFrame.Position

[Mr_Spokes]

Its close to working, but i’m still having some issues. Here is the script:

local newCFrame = script.Parent.Doors12.Door1InIn:GetPivot() * CFrame.Angles(math.rad(45), 0, math.rad(-180))
local xRotation, yRotation, zRotation = newCFrame:toEulerAnglesXYZ()
local rotation = Vector3.new(math.deg(xRotation), math.deg(yRotation), math.deg(zRotation))

script.Parent.Doors12.Door1InIn.Orientation = rotation
script.Parent.Doors12.Door1InIn.Position = newCFrame.Position

and here is the before and after of the part:


The rotation is right, but somehow the position moved inwards

Edit: somehow I think I got it to work with this:

local part = script.Parent.Doors12.Door1InIn
part:PivotTo(part:GetPivot() * CFrame.fromEulerAnglesXYZ(math.rad(90), 0, 0))

Not fully sure exactly what I did, but I think I was just able to change the angle of the pivot

Edit 2: this just fixed the actual rotation and position, not it affecting all the welds. The solution I have found for that is probably the easiest as it just involves me anchoring that part when I pivot it. For some reason, when the part is anchored, it doesn’t actually affect the welds, so I think i’m just going to use that for now.

Edit 3: I was stupid again as I just had to change this line in your code:

local newCFrame = script.Parent.Doors12.Door1InIn:GetPivot() * CFrame.fromEulerAnglesXYZ(math.rad(90), math.rad(90), 0)

Thank you, it fully works now

Edit 4: I was wrong and it doesn’t work. pivots and welds a dumb. For now i’m just going to use the anchoring solution, but if anybody finds a way to make this work then that would still be much appreciated.
