You could create Inset cabinets by using the generic Sample_F catalog in our program. When you have any Sample_F item in a floor plan, go to Global Attributes, go to Frame, and there you can add a Door Inset and a Drawer Inset.
The reason Sample_M and Sample_E do not have this option is because these are frameless catalogs. Sample_F, being framed, has the option to be inset. You can only apply inset doors to framed cabinetry.
