I can't identify which feature is cut or fill when print out in black/white, can you advice how to show different symbols fo slope automatically upon completion of my design?
The symbology of your cut/fill is determined by the style you have assigned to that feature. In using cut as an example. If you want your cut to appear as a dashed line so that you can differentiate it when printing in black and white, edit the linestyle for cut, within your Style Manager.
Within Edit Style, select Surface Feature>Symbology>Edit.
At Edit Named Symbology, select Plan Line and Edit.
Within Line Symbology, you can edit the line style of your cut so that when printed in black and white, there is a distinct difference.
