baseboards
Hi djpip,
 
I am not sure about UTC s I never used it, but in TRS2004 you open the terrain tab then go to advanced, then L click on add.   Decide where you want to add to i.e. N S E or W place your arrow over the side and L ckick once.   A new board will appear in no time as if by magic.
 
Hope this helps,
