That did work -- thank you. However, I was hoping for a faster technique, without having to model the rails and stiles separately (usually I just draw 4 lines on the face of the cabinet box so that materials can be oriented differently). If you know of any other solution let me know. Thanks.

@fredo6 See attached. Thanks.

I'm using FredoCorner to soften cabinet edges (for later rendering). Currently, my rails and stiles on cabinet doors are divided into separate faces for greater realism, but once I apply FredoCorner it merges these faces into one. I've tried different settings, including the Bevel, and always the same issue. Please let me know if I'm doing something wrong or if this is just a limitation of FredoCorner (if the latter, is it also a limitation of MindSight's Round Corner?).

Thanks.
