Once you have selected the turnout and the Active End-Point you can place it on the layout by Left-dragging on the layout. You can change the Active End-Point by a Right-click which causes the next End-Point to become Active.
If you Left-drag a turnout onto a track, the Active End-Point is aligned with the selected track. On a straight or curved track, you can flip the turnout by moving the cursor from one side of the track centerline to the other. On another turnout, the new turnout will be placed at the End-Point closest to the cursor.
You can also Right-drag to rotate the turnout on the layout.
When you press Ok, the turnout is positioned on the layout. Any tracks that are aligned with any of the turnout's End-Points will be connected to the turnout automatically.
The New button invokes the Turnout Designer dialog. This button displays a menu list of various types of turnouts and sectional track.
The Turnout Selection window will disappear while dragging on the layout if the Hide Selection Window Check Box on the Preferences dialog is set. This is useful if you have a small screen.
If the drawing scale is smaller or equal to the Label Scale then Turnouts will be labeled with their description when drawn. As well, the length of any connected Flextrack will be indicated at each End-Point.
