The Line

Delete the Connector between the Source and the SingleProc PreTest.  You might have to move the rest of your objects. Draw a rectangular with the mouse over all objects (selecting the objetcs), then left click and move and drop them further to the right.

Select the Line in the Toolbox.

Insert the Line between the Source and the station PreTest.

The first click sets the starting point, the second the end point of the Line.

Set the end point 5 grid points away from the first, then right-click to end inserting the Line.

Connect the Line with the Source and the station PreTest.
