how do i do that

download brick-builder and tick the collision option off

If can use brickbuilder or you can set one of the size axises to 0

turn collision off

this feature is for brickbuilder only
there's a little collision toggle thing like roblox's in the properties of each block

but if you open your build in the legacy workshop after disabling collisions it will re-enable them
