Disconnect Joint

Disconnecting a joint between two pieces of connected track;

Click the Split button ( ) to activate the Split command.

Place the mouse pointer right over the joint between the two track endpoints (so the "X" is shown) then Left-Click.

A blue marker will show where a split will occur, but if the cursor is a near connected joint, it will show a blue "X".

• When the Split command completes, the joint at the two track endpoints will show three lines rather than one. The three lines represent abutted, disconnected track endpoints.
• 

• Joint prior to split
• 

• Joint following split
