CanCollide not working on Dummy

Hey developers, today I tried making a dummy that you can walk through but it only works for the head and ball, the legs, torso and arms does not have the effect of CanCollide off. I have figured out that if I delete the humanoid in the dummy it works but the problem is it turn into blocks without any bevels. For example:
This is before you delete the humanoid


This is after you delete the humanoid

Thanks.

All Characters which contain Humanoids force theirs body parts CanCollide property to true, use Collision Filtering | Roblox Creator Documentation instead of CanCollide

Collision Filtering | Roblox Creator Documentation was very helpful but I cant really figure out how to make it so that players can walk through the dummy.
