Noob Question on "walk through"

Hi, I'm new to building in second life and I searched google and here for this, but I don't really know the proper term so it's been difficult finding the answer.

I'm trying to be able to walk through my object. I'm not sure is being able to "walk through" something is a setting or a script (I did search in scripts too btw). Or even if "walk through" is the correct term to search.

If anyone can point me in the right direction then it would be greatly appreciated, thanks

The word you're looking for is "phantom". You'll find a checkbox for it in the editor, on the Object tab. Happy building.
