Trying to use the Plaster-A LP sloped ends to finish off my roof however, most of the time they rotate on the snap grid to face the wrong direction. When held out in the air (away from building) it shows the correct orientation, but when dragging it to the wall it spins 180º making the whole thing not line up. Funny thing is, the back section of the house worked just fine and everything lined up. Is there a building order or work around I am just unaware of?
