This topic is really old and I remember when it first was posted.
But this is a ModuleScript that I used for making a Roundabout that you would see at a Playground
It should give you a general idea of how to make it.
Only works on LocalScripts.
local module = {}

warn("Exited")
end

while distance > 0 and attempt < 10 do
local ray = newRay(start, direction * distance)
hit, pos, origin, material = FindPartOnRay(workspace, ray, IgnoreModel, false, true)
local d = (start - pos).Magnitude
if hit and (hit:IsDescendantOf(WhitelistFolder) or hit.CanCollide) then
return hit, pos, origin, material
end
start = pos
distance = distance - d
attempt = attempt + 1
end
return hit, pos, origin, material
