A question that comes up often is how to replace the top of a kitchen base cabinet with 2 rails.
This is in fact very easy to do using the surface split command .
The disadvantage of this method is that when you change the cabinet depth the space between the rails remains constant and the rail widths change.
If you want the rail width to be constant when you change the depth of the cabinet you’ll have to use another technique.
In this video I go through the different ways of doing this:
