Spawn part without it being noclipped?

Let's say I have part called A. I have to make A spawn in random radius relative to player's torso. When indoors(surrounded by walls or underground), A spawns BEHIND the walls, which leads into it being noclipped and never seen. Now I want to make A spawn indoors and indoors only, not behind walls. Raycasting is the solution i've heard, but have no idea to achieve so, need help ASAP
