Hello 
I am currently attempting to make a 3D Map that shows players location inside a parts bounding box/area, while I was able to figure out how to get the part to attach to this part I couldn’t find any examples of keeping the CFrame movements within the part itself. I am also having an issue of the CFrame movements being inverted to what the player is doing, so if you jump the part goes down instead of up.
As you can see in this video the object is attached to the desired brick but not within the brick itself. And the movements are reversed.
Fixed This Myself a while ago.
