I have 3 mlines I use on a regular basis. Since I am not using ADT regularly, I have devised mlines to represent kitchen cabinets, vanity cabinets, and shelf-n-rod in closets. These work wonderful in these instances and since it is soooooo fast to use them, if I need to change the location I can redraw them FASTER than I can edit them...so what I can't trim them .. boo hoo hoo ...just like you can't trim a block, doesn't mean you shouldn't use them .. they have their purpose and when you finally find it, you will wonder why you ever thought differently.
