Using Raycasts along object axis

I am implementing a simple wind blower which blows wind on mouse click on the object. I used Physics.Raycast to detect the object along the wind path. Debug.draw was used to see how the lines are drawn and test. The script is as follows.

public class BlowingScript : MonoBehaviour {
	// Update is called once per frame
	void Update () {

			RaycastHit2D hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint(Input.mousePosition),;
			if (hit.collider != null) {
				if (hit.collider.CompareTag ("blower")) {
					Debug.Log ("pressed");
					Vector2 pos = Camera.main.ScreenToWorldPoint (Input.mousePosition);
					transform.position = pos;
		Debug.DrawLine (transform.position ,Vector3.up , new Color(255f,0f,0f));		// a red line
		Debug.DrawLine (transform.position ,transform.forward ,new Color(0f,255f,0f) ); //a green line



But in Run mode, the debug lines are like this

what I want to do is to send the ray/line along the transform’s axis (red arrow). But none of the lines are doing it How should my script change? Any comments on the problem, are highly valued.

Try using Debug.DrawRay rather than DrawLine?
