Hello,
I am looking for a way to get Dados to cut like this using SMA.

I will draw my panel, ribs, & rails. (the rails and ribs will be butted against each other) I will then SUBTRACT them (1/8" Deep)  from the panel and replace them. I will then analyze them to create the product. In the Composite drawing, the machining takes a 1/8" off the face of the whole panel as shown below.

To get the results I want, I have to make the Vertical Ribs .002 short so they do not touch the Top & Bottom rails, execute SMA, then in the composite drawing, stretch the dado machining to overlap Top & Bottom Rail dado machining. Is this the only way possible using SMA?
