System and methods for interfacing user in the control of elongated flexible members for use inside a patient's body is described herein. In one embodiment, a system includes a processor configured for generating a virtual representation of a catheter on a viewing screen, a first control for allowing a user to rotate the virtual representation of the catheter about a first axis, until a heading direction of the virtual representation of the catheter aligns with a heading direction of the catheter as it appears in a first fluoroscopic image, and a second control for allowing the user to rotate the virtual representation of the catheter about a second axis, until a tilt angle of the virtual representation of the catheter aligns with a tilt angle of the catheter as it appears in the first fluoroscopic image or in a second fluoroscopic image.
