Y value wont work?

[applejuices]

#pragma strict
var Firefrom : Transform;
var currentbrick: GameObject;

function Update () {
if(Input.GetButtonDown("Fire1")){
var hit : RaycastHit;
var roundpos : Vector3;



if(Physics.Raycast(Firefrom.position, Firefrom.forward, hit)){
//roundpos = 
Debug.Log(hit);
roundpos = hit.point;
roundpos *= 2.0;
roundpos = Vector3(Mathf.Round(roundpos.x), Mathf.Round(roundpos.y), Mathf.Round(roundpos.z));
roundpos /= 2.0;

Instantiate(currentbrick, roundpos , Quaternion.LookRotation(Vector3.zero));
}
}
}

This is my code to spawn a block (Soon to be things like wood or something)
it works all fine, exept that Y values will not work, and my question is, does raycast ignore cloned(Instantiated) objects? Because only way to make one on another is to click a brick’s top. So is raycast ignoring the cloned object? this is all confusing

This will move back along the Firefrom vector from hit.point by 0.01:

var pt = hit.point - Firefrom.forward.normalized * 0.01;
