What does raycast Normal mean and do?

Explanation of Surface Normal?

The surface normal is a vector, which can be imagined as a description of an arrow in 3D space. In the example given by @jody7777, the arrow is a representation of the vector that is perpendicular to (i.e. normal to; i.e. at a 90 degree angle to) the surface at that point. [image] A Vector3 is named as such because it is a vector with 3 components, normally (x, y, z). Now let’s say that the length of the arrow in the above image is 5 units. It is shown to be pointing straight up, in the posi…

part at the raycast Normal, it’s always near/at the origin

I believe you are confusing raycast result position with raycast normal in this situation.

An example use of case of raycast normal is to orient a part with the ground:

How to get the angles of a surface?

Rather than trying to convert this up vector into an angle which is also complicated it’s better to leave it I would rather use @EgoMoose advanced CFrame technique to leave it in terms of vectors. We can obtain a CFrame rotation to align the current persons “UpVector” to the new surface upvector. Here is an example script and video. The advantage of this method is that it will allow you to rotate along the new upVector without having to specify a right vector as a CFrame.fromMatrix solution. …
