offset on linerenderer unity code example

Example 1: unity look roation offset

transform.rotation = Quaternion.LookRotation(hit.normal) * Quaternion.Euler(0, 0, zAngle);

Example 2: instantiate offset unity

if ( structureIndex == 0 )
                    {    
                        var offset : Vector3 = new Vector3(0.5f, 0.5f, 0);
                        Instantiate(allStructures[structureIndex], lastHitObj.transform.position + offset, Quaternion.identity );                    
                    }
