I tried to \"texture match\" a countertop (not display cube) and it wouldn't work. Interestingly it works in reverse ie. matching from the counter to a different item. Then I discovered the \"edit countertop\" dialog allows you to change the texture, but you lose all sink cutouts, etc from the part editor. Am I missing something? Seems like part editor cuts should remain if your not resizing the part.
Go to the custom layout area ( the screen that gives you the presentation veiw option) right click mouse and you will see a change texture option for tops. Iv'e used it here and it will not delete part editor cuts in this room.HTH
