Transform.up doesnt give me it´s local up position

When I write this:

Debug.DrawLine(firstPos.position, -firstPos.up * 5, Color.red, 1);

It doesn´t go to the actual up position from the game object. It goes to the origin´s up position.

How do I get the actual up position?

Lines require start and end points, not points and directions:

Debug.DrawLine(firstPos.position, firstPos.position + firstPos.up * 5, Color.red, 1);

From Owen’s comment, you already have the Debug.DrawRay syntax there, so you can alternatively just replace DrawLine with DrawRay:

Debug.DrawRay(firstPos.position, -firstPos.up * 5, Color.red, 1);
