Bruce,
Using this method, you lose the ability to modify a breakline without
deleting all you breaklines and then redefining them all. If this is the
way you do it, perhaps you would be better off defining them as contours
instead of breaklines. The surface will still be built the same but you
wouldn't have to delete the breaklines from the database first (it lets you
overwrite or append) and you can select them by layer.
