If you are talking about in forge mode then all you have to do is press X (on default controls) while holding or targeting the object and where it says "Normal", scroll through the options until you reach "Fixed" or "Phased". Fixed mode will allow objects to float in the air, and Phased will allow most objects to pass through each other (weapons and some other things won't go through stuff). NOTE: this only is available in forge
