How can I scale or size a part on a global axis, instead of local, via script

[SalmonJumped (MacintoshIII)]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I want to grow or scale a part in a certain direction, no matter rotation.

2. What is the issue? Include screenshots / videos if possible!
   I cannot find a way to scale a parts position on a global axis, instead of local, inside of a script.
   

   

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   All solutions I’ve found relate to CFrames which don’t affect size.

You could probably achieve this affect using a server script, and the resize function for BaseParts.

The resize function works! However, I would then need to figure out how to translate a vector3 to a normal id. Unless there’s another way I can get the normal as a normal id.

local normalDir = (part:GetPivot().Position - part.Position).unit
script.Parent:Resize(normalDir,1)

It only looks like there’s a way to translate a normal id into a vector3, not the other way around. Though I might be wrong.

local size = obj.CFrame:VectorToWorldSpace(obj.Size)
size = Vector3.new(math.abs(size.Z), math.abs(size.Y), math.abs(size.X))
size = obj.CFrame:VectorToObjectSpace(size)
size = Vector3.new(math.abs(size.X), math.abs(size.Y), math.abs(size.Z))
objClone.Size = size

I figured it out a bit ago, but am answering this for other people struggling. The important parts are the 1st, 3rd, and 5th lines.
