 [[File:CPTrackDesignerSub3.gif|left]] Use this method if you are drawing a track starting from any arbitrary position. This is useful if you want to start a track or weather routing from a position that you expect to be in some time in the future, for example at a rounding mark further up the course.

Then when you begin a track or weather routing from your current position VRTool looks at your PC's clock, works out exactly how old the weather dataset is, and uses that to locate the data which applies to the current time.
