Curved Track

Creating a Curve is a two step operation. The four methods (with their accelerator keys) used to create a Curved Track are:

(Control-4) Drag from one End-Point in the direction of the Curve at that point and release. Click and Drag to position the second End-Point.
(Control-5) Drag from one of the End-Points to the Center of the Curved track and release. Click and Drag to position the second End-Point.
(Control-6) Drag from the Center of the Curved track to one of the End-Points and release. Click and Drag to position the second End-Point.
(Control-7) Drag from one End-Point to the other End-Point to form the Chord of the Curve and release. Click on the center of the track and Drag to form the Curve.

The button to the left of the Curved track button selects which method will be invoked by the Toolbar button.

In all cases, two Red arrow heads will be drawn after the first step to indicate where you can Drag to complete the second step.

A straight track will be created if the second End-Point is lined up with the first End-Point.

If the Snap Grid is enabled then the End-Points will be constrained to the grid.

Optionally, the curve center point and radius can be displayed for the Curve. This is enabled by the Move Label command.
