How would I get the thickness of a part relative to where my raycast hit from?
You should probably elaborate. Do you mean the Size, or something else?
Raycast queries return the part they intersect, if there is one. Just grab the part data from the intersection and read its Size.

Here is a simple script that does what i assume u want
-- local script in StarterPlayerScripts
local Plr = game.Players.LocalPlayer
local Mouse = Plr:GetMouse()
Mouse.Button1Down:Connect(function()
local Direction = Mouse.UnitRay.Direction.Unit * 10000
local MousePos = Mouse.Origin.Position
local Params1 = RaycastParams.new()
Params1.FilterType,Params1.FilterDescendantsInstances = Enum.RaycastFilterType.Exclude,{Plr.Character}
local Hit1 = workspace:Raycast(MousePos,Direction,Params1)
if Hit1 then
if Hit1.Instance then
Hit1.Instance.Transparency = 0.5
local StartPosition = Hit1.Position
local Params2 = RaycastParams.new()
Params2.FilterType,Params2.FilterDescendantsInstances = Enum.RaycastFilterType.Include,{Hit1.Instance}
local Hit2 = workspace:Raycast(MousePos + Direction,-Direction,Params2)
if Hit2 then
local EndPosition = Hit2.Position
local Beam = Instance.new("Beam",Hit1.Instance)
Beam.Width0 = 0.1
Beam.Width1 = 0.1
Beam.FaceCamera = true
Beam.Color = ColorSequence.new(Color3.fromRGB(255,0,0))
local Att0 = Instance.new("Attachment",Hit1.Instance)
local Att1 = Instance.new("Attachment",Hit1.Instance)
Att0.WorldPosition = StartPosition
Att1.WorldPosition = EndPosition
Beam.Attachment0 = Att0
Beam.Attachment1 = Att1
print("Rays thickness is",(StartPosition - EndPosition).Magnitude,"studs")
end
end
end
end)
Example
This script creates a ray from players cameras position towards their mouse and once it hits a part, casts another ray from the opposite direction.
Now that we have the positions of both Rays hits, just get their magnitude!
