<div style="white-space:pre-wrap">Yes. Chris Fretts, I believe, shared his need to place a table in an exact spot during a blackout. He mounted a laser pointer on a catwalk rail. During the scene change, a tech pressed the laser button while another placed the table.

I've worked with projected light before, never a laser.<br>
<br>
My advice is to make sure it is IMPOSSIBLE for the light source/laser to<br>
be shadowed or blocked. Use a crosshair in the middle of the object rather<br>
than something on or along the edge.<br>
