size of castray

[Xander Lopez]

I think the answer is probably no, but I just wanted to confirm this with someone knowledgeable...

When llCastRay executes, I believe it shoots very very tiny ray to scan objects..

refer to this post

Now, is there any possible way this tiny ray could be thicker? Perhaps.. 1 meter or 2 meters thick??

Hi! Not really possible, we don't have volumetric cast functions like box-cast or sphere-cast.

The ray from llCastRay is infinitely thin, it has literally no thickness. It's just a mathematical line/intersection.

However, you can remedy that by using multiple parallel raycasts. It's not perfect, but it's usually good enough, depending on your expected target. You should not offset the rays more than the minimum width of whatever you want to hit, which isn't always an easy answer.
