Open the Cabinet Editor.
Open the Std Base framed cabinet.
Select Construction Settings dialog box, then the Face Frames tab and Go To Page 2.
Open the Frame Thicknesses selection box just to look at it's contents (and see what is there).
Select the Define Materials button.
(At this point you could define new materials, but you really don't need to.)
Select Ok in the My Materials dialog box.
Now, open the Frame Thicknesses selection box just to look at it's contents (and see what is there). Each time you select the Define Materials button you will add a full selection of all of the dimensions you have used for your materials. So, if you originally had 1/2\", 5/8\",3/4\",1\" you will now have a list of 1/2\", 5/8\",3/4\", 1,1/2\", 5/8\",3/4\", 1. Unfortunately only some of the selections then work.
If you close the Construction Settings dialog and then re-open it all is again well.
