Dashed Line missing to line up walls

[DCortes]

New to forum still learning program, quite different than AutoCAD. For some reason when starting to draw a rectangular there used to a dashed line pop up to let you know you have reached your alignment with the other line. It has disappeared and I cannot figure out how to get it back. Does anyone know how to re-activate this.

Using Home Designer Pro 2014

Thanks in advance
